5d21c672af Moved debugging structure away from CPUs only and attached to all
devices. Debugger now creates one for each device. C++-ified most
debugger operations to hang off the debugging class, and updated
most callers. This still needs a little cleanup, but it fixes most
issues introduced when the CPUs were moved to their own devices.

Got rid of cpu_count, cpu_first, cpu_next, etc. as they were badly 
broken. Also removed cpu_is_executing, cpu_is_suspended,
cpu_get_local_time, and cpu_abort_timeslice.

Some minor name changes:
  state_value() -> state()
  state_set_value() -> set_state()

c70c5fee5a Created CPU-specific device types for all CPUs, using new macros
DECLARE_LEGACY_CPU_DEVICE and DEFINE_LEGACY_CPU_DEVICE. Changed CPUs
to be their own device types, rather than all of type CPU with a
special internal subtype. Note that as part of this process I removed
the CPU_ prefix from the ALL-CAPS device name, so CPU_Z80 is just
plain old Z80 now. This required changing a couple of names like
8080 to I8080 so that there was an alphabetic first character.

Added memory interfaces to the list of fast-access interfaces. To do
this properly I had to add a separate method to devices which is
called immediately after construction, when it is possible to perform
dynamic_casts on fully-constructed objects. (This is just internal,
no changes necessary to the devices themselves.)

Some additional notes:
 * SH2 and SH4 had typedefs that conflicted with their CPU_-less names
    so I bulk renamed to structures to sh2_state and sh4_state; RB, feel
    free to choose alternate names if you don't like 'em
 * SCSP was caught doing something to the 3rd indexed CPU. Since several
    systems that use SCSP don't even have 3 CPUs, I had no idea what
    this was supposed to do, so I changed to it reference "audiocpu"
    assuming that stv was the assumed target. This is really gross and
    should be a configuration parameter, not a hard-coded assumption.

733b797a3d Split mame.c into mame.c and machine.c, the latter containing the
running_machine definition and implementation.

Moved global machine-level operations and accessors into methods on the
running_machine class. For the most part, this doesn't affect drivers
except for a few occasional bits:

  mame_get_phase() == machine->phase()
  add_reset_callback() == machine->add_notifier(MACHINE_NOTIFY_RESET, ...)
  add_exit_callback() == machine->add_notifier(MACHINE_NOTIFY_EXIT, ...)
  mame_get_base_datetime() == machine->base_datetime()
  mame_get_current_datetime() == machine->current_datetime()

Cleaned up the region_info class, removing most global region accessors
except for memory_region() and memory_region_length(). Again, this doesn't
generally affect drivers.

41b9dbb9ac Made the machine_config a proper object. Added detokenize method to
this object which can be called multiple times to append new devices
after the initial machine configuration is set up. Updated member
variables to match new naming convention.

Changed the running_machine to take a constructed machine_config
object in the constructor, instead of creating one itself, for
consistency. Also added machine->total_colors() as a shortcut to 
machine->config->m_total_colors.

29b6b0de41 C++-ified the debugger views. Not quite architecturally where I would
like them, but it's a start. Split implementation of individual view
types out to separate files. Updated all callers.

Also:
 * fixed okim6295 memory view
 * changed emualloc to free resource pools from earliest to latest
    so that early objects can safely clean up stuff they allocated

100564d412 WARNING: There are likely to be regressions in both functionality and
performance as a result of this change. Do not panic; report issues to the
list in the short term and I will look into them. There are probably also
some details I forgot to mention. Please ask questions if anything is not
clear.

NOTE: This is a major internal change to the way devices are handled in
MAME. There is a small impact on drivers, but the bulk of the changes are
to the devices themselves. Full documentation on the new device handling
is in progress at http://mamedev.org/devwiki/index.php/MAME_Device_Basics

Defined two new casting helpers: [Aaron Giles]

  downcast<type>(value) should be used for safe and efficient downcasting
  from a base class to a derived class. It wraps static_cast<> by adding
  an assert that a matching dynamic_cast<> returns the same result in 
  debug builds.
  
  crosscast<type>(value) should be used for safe casting from one type to
  another in multiple inheritance scenarios. It compiles to a 
  dynamic_cast<> plus an assert on the result. Since it does not optimize
  down to static_cast<>, you should prefer downcast<> over crosscast<>
  when you can.
  
Redefined running_device to be a proper C++ class (now called device_t).
Same for device_config (still called device_config). All devices and
device_configs must now be derived from these base classes. This means
each device type now has a pair of its own unique classes that describe
the device. Drivers are encouraged to use the specific device types
instead of the generic running_device or device_t classes. Drivers that
have a state class defined in their header file are encouraged to use
initializers off the constructor to locate devices. [Aaron Giles]

Removed the following fields from the device and device configuration
classes as they never were necessary or provided any use: device class,
device family, source file, version, credits. [Aaron Giles]

Added templatized variant of machine->device() which performs a downcast
as part of the device fetch. Thus machine->device<timer_device>("timer")
will locate a device named "timer", downcast it to a timer_device, and
assert if the downcast fails. [Aaron Giles]

Removed most publically accessible members of running_device/device_t in
favor of inline accessor functions. The only remaining public member is
machine. Thus all references to device->type are now device->type(), etc.
[Aaron Giles]

Created a number of device interface classes which are designed to be mix-
ins for the device classes, providing specific extended functionality and
information. There are standard interface classes for sound, execution,
state, nvram, memory, and disassembly. Devices can opt into 0 or more of
these classes. [Aaron Giles]

Converted the classic CPU device to a standard device that uses the
execution, state, memory, and disassembly interfaces. Used this new class
(cpu_device) to implement the existing CPU device interface. In the future
it will be possible to convert each CPU core to its own device type, but 
for now they are still all CPU devices with a cpu_type() that specifies
exactly which kind of CPU. [Aaron Giles] 

Created a new header devlegcy.h which wraps the old device interface using
some special template classes. To use these with an existing device,
simply remove from the device header the DEVICE_GET_INFO() declaration and
the #define mapping the ALL_CAPS name to the DEVICE_GET_INFO. In their
place #include "devlegcy.h" and use the DECLARE_LEGACY_DEVICE() macro.
In addition, there is a DECLARE_LEGACY_SOUND_DEVICE() macro for wrapping
existing sound devices into new-style devices, and a 
DECLARE_LEGACY_NVRAM_DEVICE() for wrapping NVRAM devices. Also moved the
token and inline_config members to the legacy device class, as these are
not used in modern devices. [Aaron Giles]

Converted the standard base devices (VIDEO_SCREEN, SPEAKER, and TIMER) 
from legacy devices to the new C++ style. Also renamed VIDEO_SCREEN to
simply SCREEN. The various global functions that were previously used to
access information or modify the state of these devices are now replaced
by methods on the device classes. Specifically:

  video_screen_configure()             == screen->configure()
  video_screen_set_visarea()           == screen->set_visible_area()
  video_screen_update_partial()        == screen->update_partial()
  video_screen_update_now()            == screen->update_now()
  video_screen_get_vpos()              == screen->vpos()
  video_screen_get_hpos()              == screen->hpos()
  video_screen_get_vblank()            == screen->vblank()
  video_screen_get_hblank()            == screen->hblank()
  video_screen_get_width()             == screen->width()
  video_screen_get_height()            == screen->height()
  video_screen_get_visible_area()      == screen->visible_area()
  video_screen_get_time_until_pos()    == screen->time_until_pos()
  video_screen_get_time_until_vblank_start() == 
                                 screen->time_until_vblank_start()
  video_screen_get_time_until_vblank_end() == 
                                 screen->time_until_vblank_end()
  video_screen_get_time_until_update() == screen->time_until_update()
  video_screen_get_scan_period()       == screen->scan_period()
  video_screen_get_frame_period()      == screen->frame_period()
  video_screen_get_frame_number()      == screen->frame_number()

  timer_device_adjust_oneshot()        == timer->adjust()
  timer_device_adjust_periodic()       == timer->adjust()
  timer_device_reset()                 == timer->reset()
  timer_device_enable()                == timer->enable()
  timer_device_enabled()               == timer->enabled()
  timer_device_get_param()             == timer->param()
  timer_device_set_param()             == timer->set_param()
  timer_device_get_ptr()               == timer->get_ptr()
  timer_device_set_ptr()               == timer->set_ptr()
  timer_device_timeelapsed()           == timer->time_elapsed()
  timer_device_timeleft()              == timer->time_left()
  timer_device_starttime()             == timer->start_time()
  timer_device_firetime()              == timer->fire_time()

Updated all drivers that use the above functions to fetch the specific
device type (timer_device or screen_device) and call the appropriate
method. [Aaron Giles]

Changed machine->primary_screen and the 'screen' parameter to VIDEO_UPDATE
to specifically pass in a screen_device object. [Aaron Giles]

Defined a new custom interface for the Z80 daisy chain. This interface
behaves like the standard interfaces, and can be added to any device that
implements the Z80 daisy chain behavior. Converted all existing Z80 daisy
chain devices to new-style devices that inherit this interface.
[Aaron Giles]

Changed the way CPU state tables are built up. Previously, these were data
structures defined by a CPU core which described all the registers and how
to output them. This functionality is now part of the state interface and
is implemented via the device_state_entry class. Updated all CPU cores
which were using the old data structure to use the new form. The syntax is
currently awkward, but will be cleaner for CPUs that are native new 
devices. [Aaron Giles]

Converted the okim6295 and eeprom devices to the new model. These were
necessary because they both require multiple interfaces to operate and it
didn't make sense to create legacy device templates for these single cases.
(okim6295 needs the sound interface and the memory interface, while eeprom
requires both the nvram and memory interfaces). [Aaron Giles]

Changed parameters in a few callback functions from pointers to references
in situations where they are guaranteed to never be NULL. [Aaron Giles]

Removed MDRV_CPU_FLAGS() which was only used for disabling a CPU. Changed
it to MDRV_DEVICE_DISABLE() instead. Updated drivers. [Aaron Giles]

Reorganized the token parsing for machine configurations. The core parsing
code knows how to create/replace/remove devices, but all device token
parsing is now handled in the device_config class, which in turn will make
use of any interface classes or device-specific token handling for custom
token processing. [Aaron Giles]

Moved many validity checks out of validity.c and into the device interface
classes. For example, address space validation is now part of the memory
interface class. [Aaron Giles]

Consolidated address space parameters (bus width, endianness, etc.) into
a single address_space_config class. Updated all code that queried for
address space parameters to use the new mechanism. [Aaron Giles]

ec586731b9 Made device->tag and devconfig->tag into private member variables (m_tag).
Added inline tag() function to return a const char * version. Updated
callers to use this instead of directly accessing tag.cstr() which
was awkward.

e738b79785 Correct a long-standing design flaw: device configuration state
is now separate from runtime device state. I have larger plans
for devices, so there is some temporary scaffolding to hold
everything together, but this first step does separate things
out.

There is a new class 'running_device' which represents the
state of a live device. A list of these running_devices sits
in machine->devicelist and is created when a running_machine
is instantiated.

To access the configuration state, use device->baseconfig()
which returns a reference to the configuration.

The list of running_devices in machine->devicelist has a 1:1
correspondance with the list of device configurations in
machine->config->devicelist, and most navigation options work
equally on either (scanning by class, type, etc.)

For the most part, drivers will now deal with running_device
objects instead of const device_config objects. In fact, in
order to do this patch, I did the following global search &
replace:

  const device_config -> running_device
  device->static_config -> device->baseconfig().static_config
  device->inline_config -> device->baseconfig().inline_config

and then fixed up the compiler errors that fell out.

Some specifics:

  Removed device_get_info_* functions and replaced them with
  methods called get_config_*.
  
  Added methods for get_runtime_* to access runtime state from
  the running_device.
  
  DEVICE_GET_INFO callbacks are only passed a device_config *.
  This means they have no access to the token or runtime state
  at all. For most cases this is fine.
  
  Added new DEVICE_GET_RUNTIME_INFO callback that is passed
  the running_device for accessing data that is live at runtime.
  In the future this will go away to make room for a cleaner
  mechanism.
  
  Cleaned up the handoff of memory regions from the memory
  subsystem to the devices.

d061ced592 Created new template class tagged_list which manages a simple list
along with a tagmap. Changed memory regions, input ports, and devices
to use this class. For devices, converted typenext and classnext
fields into methods which dynamically search for the next item.
Changed a number of macros to use the features of the class, removing
the need for a bunch of helper functions.

2010-01-12 06:54:57 +00:00

4498faacd9 First round of an attempted cleanup of header files in the system.
- Created new central header "emu.h"; this should be included
    by pretty much any driver or device as the first include. This
    file in turn includes pretty much everything a driver or device
    will need, minus any other devices it references. Note that
    emu.h should *never* be included by another header file.
 - Updated all files in the core (src/emu) to use emu.h.
 - Removed a ton of redundant and poorly-tracked header includes
    from within other header files.
 - Temporarily changed driver.h to map to emu.h until we update
    files outside of the core.

Added class wrapper around tagmap so it can be directly included
and accessed within objects that need it. Updated all users to
embed tagmap objects and changed them to call through the class.

Added nicer functions for finding devices, ports, and regions in
a machine:

   machine->device("tag") -- return the named device, or NULL
   machine->port("tag") -- return the named port, or NULL
   machine->region("tag"[, &length[, &flags]]) -- return the
      named region and optionally its length and flags
      
Made the device tag an astring. This required touching a lot of 
code that printed the device to explicitly fetch the C-string
from it. (Thank you gcc for flagging that issue!)
2010-01-10 00:29:26 +00:00
Aaron Giles
a92de5930c Extended the astring class wrapper into something useful, and
useable as a stack object. Also designed the interfaces to allow
for chaining operations. And added a casting operator to const
char * for seamless use in most functions that take plain old C
strings.

Changed all uses of astring to use the object directly on the
stack or embedded in objects instead of explicitly allocating 
and deallocating it. Removed a lot of annoying memory management
code as a result.

Changed interfaces that accepted/returned an astring * to
use an astring & instead.

Removed auto_alloc_astring(machine). Use 
auto_alloc(machine, astring) instead.

91a1b8d634 NOTE: This change requires two new osd functions: osd_malloc() and
osd_free(). They take the same parameters as malloc() and free().

Renamed mamecore.h -> emucore.h.

New C++-aware memory manager, implemented in emualloc.*. This is a
simple manager that allows you to add any type of object to a
resource pool. Most commonly, allocated objects are added, and so
a set of allocation macros is provided to allow you to manage
objects in a particular pool:

  pool_alloc(p, t) = allocate object of type 't' and add to pool 'p'
  pool_alloc_clear(p, t) = same as above, but clear the memory first
  pool_alloc_array(p, t, c) = allocate an array of 'c' objects of type
                              't' and add to pool 'p'
  pool_alloc_array_clear(p, t, c) = same, but with clearing
  pool_free(p, v) = free object 'v' and remove it from the pool

Note that pool_alloc[_clear] is roughly equivalent to "new t" and
pool_alloc_array[_clear] is roughly equivalent to "new t[c]". Also
note that pool_free works for single objects and arrays.

There is a single global_resource_pool defined which should be used
for any global allocations. It has equivalent macros to the pool_*
macros above that automatically target the global pool.

In addition, the memory module defines global new/delete overrides
that access file and line number parameters so that allocations can
be tracked. Currently this tracking is only done if MAME_DEBUG is
enabled. In debug builds, any unfreed memory will be printed at
the end of the session.

emualloc.h also has #defines to disable malloc/free/realloc/calloc.
Since emualloc.h is included by emucore.h, this means pretty much
all code within the emulator is forced to use the new allocators.
Although straight new/delete do work, their use is discouraged, as
any allocations made with them will not be tracked.

Changed the familar auto_alloc_* macros to map to the resource pool
model described above. The running_machine is now a class and contains
a resource pool which is automatically destructed upon deletion. If
you are a driver writer, all your allocations should be done with
auto_alloc_*.

Changed all drivers and files in the core using malloc/realloc or the 
old alloc_*_or_die macros to use (preferably) the auto_alloc_* macros 
instead, or the global_alloc_* macros if necessary.

Added simple C++ wrappers for astring and bitmap_t, as these need
proper constructors/destructors to be used for auto_alloc_astring and
auto_alloc_bitmap.

Removed references to the winalloc prefix file. Most of its 
functionality has moved into the core, save for the guard page 
allocations, which are now implemented in osd_alloc and osd_free.

9eda9e163e More memory system cleanup. Removed SMH_* macros entirely. In
their place are a series of expanded macros and new memory
installation helpers. Some mappings below (not all are new):

   AM_READ(SMH_RAM)                       -> AM_READONLY
   AM_WRITE(SMH_RAM)                      -> AM_WRITEONLY
   AM_READWRITE(SMH_RAM, SMH_RAM)         -> AM_RAM
   AM_READ(rhandler) AM_WRITE(SMH_RAM)    -> AM_RAM_READ(rhandler)
   AM_READ(SMH_RAM) AM_WRITE(whandler)    -> AM_RAM_WRITE(whandler)
   AM_DEVREAD(tag, rhandler) AM_WRITE(SMH_RAM) 
                                  -> AM_RAM_DEVREAD(tag, rhandler)
   AM_READ(SMH_RAM) AM_DEVWRITE(tag, whandler) 
                                  -> AM_RAM_DEVWRITE(tag, whandler)

   AM_READ(SMH_ROM)                       -> AM_ROM
   AM_WRITE(SMH_ROM)                      -> (was a no-op)

   AM_READ(SMH_NOP)                       -> AM_READNOP
   AM_WRITE(SMH_NOP)                      -> AM_WRITENOP
   AM_READWRITE(SMH_NOP, SMH_NOP)         -> AM_NOP

For dynamic memory handler installation of the various types,
use the new functions:

   memory_unmap_read()
   memory_unmap_write()
   memory_unmap_readwrite() -- unmaps a section of address space

   memory_nop_read()
   memory_nop_write()
   memory_nop_readwrite() -- nops a section of address space

Cleaned up the internals of the address_map_entry structure, and
also normalized the way the address map macros work to remove a
lot of redundancy.

Fixed the logical/physical issue by having the cheat system always
work at the physical layer and output cheats that explicitly point
to the physical space.

Subject: MAME cheat search engine

This is a diff of my cheat search engine with help of Pugsy.  
This is only a first part, not has the same functions of the old search engine, but is better than nothing

I have update the search engine to support search of byte, word, dword
and qword signed and unsigned.

a70fdf00a1 CPU interface organization shuffle. The file cpuintrf.h now merely
describes the interface, but does not contain any implementation.
All remaining bits of implementation have been migrated either to
cpuexec.c or to debugcpu.c. Specifically, cpu_dasm() is now
debug_cpu_disassemble(), and cpu_set_dasm_override() is now
debug_cpu_set_dasm_override(). Also moved memory_address_physical()
to debug_cpu_translate(), since it was only ever used for
debugging.

Changed all CPU and sound cores to use memory_find_address_space()
instead of cpu_get_address_space(). The former is reliable even
during early initialization when the CPU cores generally need it.

Removed the dummy CPU core and cpuintrf.c.

Changed the core execution loop to directly call the execute
function instead of using the inline helper (which has been removed).

5630547540 More device normalization:
cpu_get_info_* -> device_get_info_*
  cpu_set_info_* -> device_set_info_*
  cpu_reset      -> device_reset

Removed the cputype_get_* macros as they are not necessary.

Removed cpuintrf_init() which is no longer necessary.

98c40f06db Made CPUs into proper devices. CPUs are now added in the
machine configuration just as any other device, and the
standard CPU configuration is performed via the inline
configuration macros.

Change cpu_type from an enumeration into a pointer to the
CPU's get_info function, very similar to device behavior.
For now all CPUs are declared in cpuintrf.h, but 
eventually they should be declared in the CPU's header
file, and the driver should #include that header.

Added function cpu_get_type() to return the CPU type.

Changed several cpu_* functions into macros that call
through to the equivalent device_* function.

The device system now maintains a parallel list of devices
based on type, for faster iteration through all devices
of a given type.

Cleaned up code that looped over CPUs via the machine->cpu
array to now loop using the type-based device list.

Removed start/stop/reset/nvram functions from the 
device_config in favor of grabbing them as needed.

Cleaned up the generic interrupt_enable code to work with
CPU devices instead of numbers.

Mapped the devtag_* functions to device_* functions via
macros instead of parallel implementations.

d87ef8f79b Here's the big one....
Added new function cpuexec_describe_context(machine) which can be
used in logerror() and other printf-style functions to return a
description of the current CPU/PC given only the machine. Changed
several dozen sites to use this instead of directly interrogating
the activecpu.

Removed all other uses of activecpu throughout the system. Removed
activecpu from the machine structure to prevent future abuse.

Removed cpu_push_context() and cpu_pop_context(), and all call
sites.

Voodoo devices now require a CPU to be defined in the configuration
in order to know whom to steal cycles from or stall when FIFOs get
full. Updated all voodoo users to specify one.

CPD1869 devices now also require a CPU to be defined in the
configuration, in order to know which CPU's registers to fetch.
Updated all cdp1869 users to specify one.

Many other small changes to make this all work.

Subject: [patch] Deprecat.h cleanup

Hi mamedev,

This patch changes some global Machine references to use machine,
device->machine, ... instead, and removes any unneeded #include
"deprecat.h" lines as well (about 10% of them in fact).  It was
generated using the attached script, and then reverting some cases
where it was overzealous.

3c6eacc96f Changed save state system to accept machine parameters where
appropriate, and to keep all global variables hanging off the
machine structure. Once again, this means all state registration
call sites have been touched:

  - state_save_register_global* now takes a machine parameter
  - state_save_register_item* now takes a machine parameter
  - added new state_save_register_device_item* which now uses
     the device name and tag to generate the base name

Extended the fake sound devices to have more populated fields.
Modified sound cores to use tags from the devices and simplified
the start function.

Renumbered CPU and sound get/set info constants to align with
the device constants, and shared values where they were perfectly
aligned.

Set the type field in the fake device_configs for CPU and sound
chips to a get_info stub which calls through to the CPU and sound
specific get_info functions. This means the device_get_info()
functions work for CPU and sound cores, even in their fake state.

Changed device information getters from device_info() to
device_get_info() to match the CPU and sound macros.

30aa31f163 More debugger changes.
Added the concept of 'subviews' to the debugger views. The core
now creates a list of possible subviews, and the OSD can select
between them. This removes code from the OSD that was previously
required to find all possible memory and disassembly views.

Added machine parameters to debugger console output functions.

Fixed some oddities in the memory view.

Moved globals to hang off of the machine structure.

Fixed bug where the visiblecpu was not updated immediately upon
a break.

d924407859 Big debugger cleanup.
Important note for OSD ports: the get/set property functions have 
been retired for debug_views. Instead, there are specific functions
to perform each get/set operation. In addition, the format of the
update callback has changed to pass the osd private data in, and
the update callback/osd private data must be passed in at view
allocation time. And osd_wait_for_debugger() now gets a CPU object
instead of the machine.

Removed extra debugger tracking for address spaces and added some
of the useful data to the address_space structure. Updated all
debugger commands and views to use CPU and address space objects
where appropriate.

Added new memory functions for converting between bytes and
addresses, and for performing translations for a given address
space. Removed debugger macros that did similar things in favor
of calling these functions.

Rewrote most of the memory view handling. Disasm and register views
still need some additional tweaking.

as well as a per-symbol ref. Debugcpu is now clear of active
CPU references and global Machine references.

5816061f8e Debugger interfaces cleanup. Still more to do but this compiles and
works. Added callback parameters to the expression engine. Improved
CPU parsing so you can use a CPU tag or index in most commands that
take one. Switched to passing CPU and address space objects around
where appropriate. Lots of other minor tweaks.

371cd0a56d Another big one.
Moved memory global state into a struct hanging off of the machine.
Updated almost all memory APIs to take an address_space * where
appropriate, and updated all callers. Changed memory internals to
use address spaces where appropriate. Changed accessors to point
to the memory_* functions instead of the address space-specific
functions. Improved internal handling of watchpoints.

Added cputag_* functions: cputag_reset(), cputag_get_index(),
cputag_get_address_space(). These just expand via macros to an
initial fetch of the CPU via cputag_get_cpu() followed by the
standard CPU call.

Added debugger_interrupt_hook() and debugger_exception_hook() calls
which intelligently look at the debugger flags before calling.

Did minimal cleanup of debugger, mainly moving CPU-specific data
to hang off of the CPU classdata for more direct access.

63d10ee9bf Massive API cleanup/change. The primary goal is that all CPU-
related APIs now take a device pointer instead of an index.
All functions that take a CPU device are prefixed with cpu_*
All functions that are globally related to cpu execution
are prefixed with cpuexec_*. Below is a list of some of the 
mappings:

  cpu_boost_interleave     -> cpuexec_boost_interleave
  cpunum_suspend           -> cpu_suspend
  cpunum_resume            -> cpu_resume
  cpunum_is_suspended      -> cpu_is_suspended
  cpunum_get_clock         -> cpu_get_clock
  cpunum_set_clock         -> cpu_set_clock
  cpunum_get_clockscale    -> cpu_get_clockscale
  cpunum_set_clockscale    -> cpu_set_clockscale
  cpunum_get_localtime     -> cpu_get_local_time
  cpunum_gettotalcycles    -> cpu_get_total_cycles
  activecpu_eat_cycles     -> cpu_eat_cycles
  activecpu_adjust_icount  -> cpu_adjust_icount
  cpu_trigger              -> cpuexec_trigger
  cpu_triggertime          -> cpuexec_triggertime
  cpunum_set_input_line    -> cpu_set_input_line
  cpunum_set_irq_callback  -> cpu_set_irq_callback

In addition, a number of functions retain the same name but
now require a specific CPU parameter to be passed in:

  cpu_yield
  cpu_spin
  cpu_spinuntil_time
  cpu_spinuntil_int
  cpu_spinuntil_trigger
  cpu_triggerint

Merged cpuint.c into cpuexec.c. One side-effect of this
change is that driver reset callbacks are called AFTER the
CPUs and devices are reset. This means that if you make
changes to the CPU state and expect the reset vectors to
recognize the changes in your reset routine, you will need
to manually reset the CPU after making the change (since it
has already been reset).

Added a number of inline helper functions to cpuintrf.h for
managing addresses

Removed cpu_gettotalcpu(). This information is rarely needed
outside of the core and can be obtained by looking at the
machine->cpu[] array.

Changed CPU interrupt acknowledge callbacks to pass a CPU 
device instead of machine/cpunum pair.

Changed VBLANK and periodic timer callbacks to pass a CPU
device instead of machine/cpunum pair.

Renamed all information getters from cpu_* to cpu_get_* and
from cputype_* to cputype_get_*.
