Sega Mega Drive bootlegs in their own driver (drivers/megadriv_acbl.c), as in current MAME (#2175)

Browse Source 
Phase 2.3/5 of the Sega VDP / segac2.c clean-up: the coin-op bootlegs of
Mega Drive games move from drivers/segac2.c to drivers/megadriv_acbl.c,
with the board variants of current MAME, and the nine new sets we have
the ROMs for are added. The Mega Drive part stays shared with the other
Mega Drive based boards (includes/segac2.h).

- Moved: aladmdb, barek2ch, barek3mb, jparkmb, sonic2mb, sonic3mb,
  twinktmb (titles as in current MAME). Same code paths as before: frames
  and audio identical to the previous build.
- New: barekch, barek2mb, barek3mba, biohzdmb, bk3ssrmb, mk3mdb, srmdb,
  srssf2mb, ssf2mdb.
- The board variants of MAME: the version register, 6 button pads (MAME's
  TH counter with the 1.5ms timeout), the 3rd I/O port coins, the DIP
  switches at 0x770070 of the scrambled boards (and the coins at 0x770078
  of biohzdmb), the 6MB linear map of ssf2mdb, the PIC16C57 of barek2mb (emulated, with its latches; the
  68000 byte writes reach both halves of the bus as on the real CPU; T0
  is not connected), the simulated PIC of barek3mba.
- The new sets take V-INT / H-INT through the VDP interrupt enables, as on
  the real hardware (mk3mdb took a V-INT before its RAM vector was set
  and crashed); the moved sets keep the old mode.
- Big-endian hosts: the descrambling of the bootlegs uses BYTE_XOR_LE,
  and the PIC program of barek2mb is put in the host order the PIC core
  fetches its opcodes in.
- Mega Drive VDP: in H32 mode the sprite table base uses bit 0 of
  register 5 (AT9), as on the real VDP and in MAME; it was always masked
  as in H40 (ssf2mdb sets 0x6d in H32: the fighters were missing; the sprites
  of mt_bbros were garbled).
- PIC16C5x core: the PC wraps at the end of the program memory (the 2K
  parts start at 0x7ff and ran past the ROM), and the save states no
  longer register the ports and STATUS through R.picRAM before it is set
  (a NULL pointer: saving a game with a PIC crashed). They are in the data
  RAM, saved with the CPU memory.
- Save states: the pad, frame counter and PIC latch state.
- Metadata: mame2003-plus.xml (the bootleg entries regenerated),
  CHANGELOG.md.

* Sega Mega Play: the BIOS overlay is transparent on colour 0 of both its palettes and covers its borders, as in current MAME (the boot logo screen was hidden behind a green background)
* Sega Mega Drive based bootlegs: their own driver (`drivers/megadriv_acbl.c`, as in current MAME), with the board variants of current MAME (the 6 button pads, the DIP switches at 0x770070 of the scrambled boards, the 3rd I/O port coins, the PIC16C57 of `barek2mb`); the new sets take their V-INT / H-INT through the VDP interrupt enables as on the real hardware (Mortal Kombat 3 crashed at boot), the descrambling of the bootlegs and the PIC of `barek2mb` now also work on big-endian hosts
* Sega Mega Drive VDP: in H32 mode the sprite table base uses bit 0 of register 5, as on the real VDP (the fighters of Super Street Fighter II were missing, the sprites of Bonanza Bros. on Mega-Tech were garbled)
* PIC16C5x CPU core: the program counter wraps at the end of the program memory (the 2K parts start at 0x7ff and ran past the ROM), and the save states no longer register the ports and STATUS through a NULL pointer (the save of a game with a PIC crashed); these are in the data RAM, saved with the CPU memory
* Save states (netplay, RunAhead with a second instance) of the Mega Drive based boards: the Z80 RAM and bus state and the Mega-Tech / Mega Play BIOS registers and RAM are saved (Gunstar Heroes and Mazin Wars Mega Play went out of sync after loading a state in a new instance); the SN76496 PSG is saved, and the YM2612 DAC enable is restored from its own register (0x2b, it was read from 0x2d)
* Sega System 18 (also Moonwalker): the VDP palette writes no longer overflow the System 16 palette RAM (they corrupted the memory after it, e.g. garbled graphics in Shadow Dancer), and the sprite shadows over the VDP layer no longer index past the palette
* Save states (RunAhead, netplay) of the Sega System 18 hardware: the RF5C68 PCM, the YM2612/YM3438 envelope, LFO, frequency and timer state, the VDP layer, the sound ROM bank
