- Rearranged decoding behavior.
- Updated code style to MAME standards.
- Tested each single-word opcode with custom ROMs.
(This is a precursor to other major dsp56k changes I have made. I just gotta' get plygonet commanders up and running to do some tests)

- TGP now correctly uses table roms (model1/2 updated accordingly)
- removed FIFO hack on srallyc (game now runs)
- added analog ports reading for model 2A/B/C
- fixed some loading instructions in the TGP. that fixes srallyc automatic transmission bug

Tagged all CPUs. Now I will take a break until my fingers stop
cramping. :)

Added validity checks to ensure no duplicate sound or CPU tags.
Fixed several duplicate sound tags from the last checkin.
-listxml now outputs the tag names for CPUs and sound chips.

well, the fix is not that but changing them this way:
program_write_dword_32le(i960.r[I960_FP]-16, i960.PC);
program_write_dword_32le(i960.r[I960_FP]-12, i960.AC);
in take_interrupt.
It seems it came from a partial fix in the ret instruction. the manual says that PC is saved at FP-16 and AC at FP-12
it was reversed in mame, so when trying to fix it, i suppose Ernesto forgot to change the push too.
I've tested this fix and apart from having daytona working, pilot kids 2A works too (that I think has been broken for ages).

MDRV_SOUND_ADD. All sound chips must now include a tag.
Laboriously changed all existing drivers to define a
unique tag for each sound chip.
CPUs are next, but will require a more hands-on manual
process to produce reasonable tags.

properly ignore the "break into debugger" keypress and not allow
related characters to filter through. Removed some hacks related to
making that work in the past.
Changed osd_wait_for_debugger() to take a machine parameter and a
"firsttime" parameter, which is set to 1 the first time the function
is called after a break. The Windows debugger uses this to ensure
that the debugger has focus when you break into it.

EEPROM data, and the size is in terms of units, not bytes. Updated all
drivers accordingly.
Changed the ROM loading code to actually alter the region flags based
on the CPU endianness and bus width when creating the region, rather
than fixing them up on the fly. This means that callers to
memory_region_flags() will get the correct results.
Changed the expression engine to use two callbacks for read/write rather
than relying on externally defined functions.
Expanded memory access support in the expression engine. Memory accesses
can now be specified as [space][num]<size>@<address>. 'space' can be
one of the following:
p = program address space of CPU #num (default)
d = data address space of CPU #num
i = I/O address space of CPU #num
o = opcode address space of CPU #num (R/W access to decrypted opcodes)
r = direct RAM space of CPU #num (always allows writes, even for ROM)
e = EEPROM index #num
c = direct REGION_CPU#num access
u = direct REGION_USER#num access
g = direct REGION_GFX#num access
s = direct REGION_SOUND#num access
The 'num' field is optional for p/d/i/o/r, where is defaults to the
current CPU, and for e, where it defaults to EEPROM #0. 'num' is required
for all region-related prefixes. Some examples:
w@curpc = word at 'curpc' in the active CPU's program address space
dd@0 = dword at 0x0 in the active CPU's data address space
r2b@100 = byte at 0x100 from a RAM/ROM region in CPU #2's program space
ew@7f = word from EEPROM address 0x7f
u2q@40 = qword from REGION_USER2, offset 0x40
The 'size' field is always required, and can be b/w/d/q for byte, word,
dword, and qword accesses.

- Fixed TRAPA and some versions of FMOV
- Improved disassembly for MOV.W, MOVA, MOV.L, FIPR, and FSCA.

- All games on all drivers should work as before except "colmns97" and "stress" which crash due to sound system trouble.
- All idle skips are still included. They are quite a bit less effective than they were on the interpreter, but they still give a boost.
- Fast RAM bypass is not included yet so this does not represent final performance. That said, it's consistently faster than the interpreter even now. Example: sfiii3 on 0.126 gets 609% on the interpreter and 961% on the DRC.
Major thanks to Aaron for his assistance with several sticky core bugs and other issues encountered writing this.

lurking. If you run into anything odd, please let me know.
Added new module uiinput.c which manages input for the user interface.
The OSD is responsible for pushing mouse events and character events
to this interface in order to support mouse movement and text-based
input (currently only used for the select game menu). Added support
for navigating through the menus using the mouse.
[Nathan Woods, Aaron Giles]
Redesigned the UI menus so that they can maintain a richer state. Now
the menus can be generated once and reused, rather than requiring them
to be regenerated on each frame. All menus also share a comment eventing
system and navigation through them is managed centrally. Rewrote all the
menus to use the new system, apart from the cheat menus, which are now
disabled. Reorganized the video menu to make it easier to understand.

- Roll back older periodic function
Now standard/old format work in this function
Otherwords, several operations which doesn't exist in older
function and added recently are now disabled
- Separated load_cheat_code() to 3 indipendent functions
And added new cheat options, "Load New/Standard/Old Format Code"
(Default : load all format codes)
NOTE : delete all cheat options in the database before start
or reload default options (Shift + Reload key)
in cheat general menu
- Added format strings structure to accept huge size strings
in loading a database to prevent from breaking other strings
- Changed Link in new format
Label code is now "Link-Label" and sub-label is "Label-Sub-Link"
"Standard-Link" is no longer label
- Added choose_label_index() to manage label selection
- Fixed build_label_index_table() to prevent from crashing
And disabled to build label index table in case of
standard/old format
- Fixed memory free problem in case of standard/old code
- Fixed several reported/found bugs
