Added option to clear dynamic_arrays; on gcc this should assert if not
done on POD (which is unsafe to memset).

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.

- 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!)

debugger always passes 0 for this. unidasm has been updated to accept a
mode parameter, which is passed for the options.

has_extended_io flag (switch between 0x40 and 0x100 I/O registers), the latter is used by the Taito JC HC11 CPU only at the current time.

Subject: [patch] Migrate CPU defines to cpu header files
Hi mamedev,
This patch migrates all the CPU definitions into the cpu header files.
The #defines and CPU_GET_INFO declarations were added by hand to the
cpu cores in the first patch, plus a few partly related fixes to the
non-DRC cores. The second patch was produced by the attached script
which inserts all needed #includes, except for two that were added by
hand in the first patch. The first patch also removed an extra define
of N2A03_DEFAULTCLOCK that would have caused problems with the second
patch.

macro from the source code. All MAME builds now include
the debugger, and it is enabled/disabled exclusively by
the runtime command-line/ini settings. This is a minor
speed hit for now, but will be further optimized going
forward.
Changed the 'd' suffix in the makefile to apply to DEBUG
builds (versus DEBUGGER builds as it did before).
Changed machine->debug_mode to machine->debug_flags.
These flags now indicate several things, such as whether
debugging is enabled, whether CPU cores should call the
debugger on each instruction, and whether there are live
watchpoints on each address space.
Redesigned a significant portion of debugcpu.c around
the concept of maintaining these flags globally and a
similar, more complete set of flags internally for each
CPU. All previous functionality should work as designed
but should be more robust and faster to work with.
Added new debugger hooks for starting/stopping CPU
execution. This allows the debugger to decide whether
or not a given CPU needs to call the debugger on each
instruction during the coming timeslice.
Added new debugger hook for reporting exceptions.
Proper exception breakpoints are not yet implemented.
Added new module debugger.c which is where global
debugger functions live.

(DEBUGGER) which sets
a new compile-time define (ENABLE_DEBUGGER). This means that MAME_DEBUG no longer means
"enable debugger", it simply enables debugging features such as assertions and debug code
in drivers.
Also removed the various levels of opbase protection in memory.h and always just turned
on full bounds checking.
Fixed build break due to missing ampoker.lay -> ampoker2.lay renaming.
