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.
