Fixed colours in Battle City [Roberto Gandola]

Slight change to the Arcadia Driver [Nathan Woods]
src/drivers/arcadia.c:
src/includes/amiga.h:
src/machine/amiga.c:
- Refactors code specific to the Arcadia arcade system and the Amiga
computer out of src/machine/amiga.c into callbacks. This allowed me to
get rid of all #ifdef MESS code out of src/machine/amiga.c

ST-V updates [Angelo Salese]
-Fixed a bug with the VDP-1 ram reading,
SH-2 can do byte or word access, it's implicit that can't do long word access.
This fixes the Steep Slope Sliders booting so the game now works.
-VDP-1 PTM's "draw by request" was actually causing sprites to flicker in
kiwames,reversed back to old implementation until I or somebody else understand
what the current issue is (clear_framebuffer?)
-Finished the game header update,let me know if you like/don't like the system
used for the description of the games.
-fixed a ST-V visible area incorrectness which was causing Virtual Mahjong 2 to
crash after the sound ram check
-fixed a window effect bug in Double-density interlace mode,this fixes some
graphics in vmahjong & myfairld.
-Guessed a bitmap positioning issue in double-density interlace mode,this fixes
the NBG1 positioning in myfairld.
-My Fair Lady now works but only with sound disabled.I have not removed the
NOT_WORKING status due to that.

New Sound Functionality [Derrick Renaud]
Took Frank Palazzolo's DISCRETE_FILTER2 code and made it work outside of the
discrete system.
See sound\filter.h for new functions.

Added op-amp bandpass filtering circuit to sound\namco54.c

Game Driver Changes
* bosco, galaga, polepos, xevious - added proper filters to new Namco54 noise
source.

Fixed Priority in Lot Lot [Pierpaolo Prazzoli]

Decrypted Sukeban Jansi Ryuko [Nicola Salmoria]

ARM7 CPU core [Steve Ellenoff]

G65816 CPU core patch [Nathan Woods]
src/cpu/g65816/g65816.c:
src/cpu/g65816/g65816.h:
src/cpu/g65816/g65816ds.c:
src/cpu/g65816/g65816ds.h:
src/cpu/g65816/g65816op.h:
- Cleaned up the code a bit; make some functions static and added
step over/out support to the disassembler.

53c810 SCSI:
- Fixed single-stepping mode DMA

Model 3:
