- 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!)
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.

* Input ports are now maintained hierarchically. At the top
level are input ports, which contain a list of fields. Each
field represents one or more bits of the port. Certain fields
such as DIP switches and configuration switches contain a
list of settings, which can be selected. DIP switch fields
can also contain a list of DIP switch locations.
* Normalized behavior of port overrides (via PORT_INCLUDE or
by defining multiple overlapping bits). All fields within a
port are kept in strict increasing bit order, so altered DIP
switches are now kept in the appropriate order. This addresses
MAMETesters bug 01671.
* Live port state is now fully separate from configured
state. This is manifested in a similar way to devices, where
a const list of ports can be managed either offline or live.
Each port has a pointer to an opaque set of live state which
is NULL when offline or valid when live. Each port also has
a running_machine * which is also NULL when offline.
* Because of this new arrangement, the conversion from tokens
to a list of ports now requires reasonably complex memory
allocation, so these port lists must be explicitly allocated
and freed (they are not mantained by automatic resource
allocation).
* Custom and changed callbacks now take a pointer to a field
config instead of a running machine. This provides more
information about what field triggered the change notification.
The machine can be found by referenced field->port->machine.
* The inptport.c module has been cleaned up and many
ambiguities resolved. Most of this is internal, though it did
result in osd_customize_inputport_list() being changed to
osd_customize_input_type_list(). The parameter to this function
is now a linked list instead of an array, and the structures
referenced have been reorganized somewhat.
* Updated config.c to pass machine parameters to its callbacks.
* Updated validity checks, XML output, and UI system to handle
the new structures.
* Moved large table of default input settings to a separate
include file inpttype.h.
* Removed gross hacks in trackfld and hyperspt NVRAM. These
may be broken as a result.
- removed years from copyright notices
