All MAME <-> Netlist interfacing is now done in the machine device driver. This 
a) ensures, that the interface logic is in one place and easy to understand
b) ensures, that netlists represent the hardware and not what has to be done
   to hook the hardware up in MAME.
   
The interface part is considered to be relatively stable. Consequently, enabled netlist audio filtering in 1942.
(MESS) gl4000: fixed screen size. (nw)
(MESS) apple3: extended addressing applies to all $x1 opcodes.  SOS apps now start up.  [R. Belmont]
twincobr.c: fix flipscreen after core changes, cleanups [Alex Jackson]
(MESS) nes_mmc5: * hacked around the limitations of our PPU code, so to support the 
different CHR registers
* improved PRG-RAM handling
* first attempt to add split screen mode, still broken
no whatsnew

the hack only deals with the way MMC-5 monitors PPU activity, not with the actual effect. when
I get to the point of completing my not-yet-abandoned PPU rewrite, the new calls in ppu2c0x.h
will go away...
(MESS) nes_mmc5: misc wip [Fabio Priuli]
* hacked around the limitations of our PPU code, so to support the different CHR registers
* implemented Extended Attribute Mode (Ex1)
* improved PRG-RAM handling
* simplified NT-RAM handling
* first attempt to add split screen mode, still broken

out of whatsnew: this was for sake of messnew inclusion ;)
improved irqs
(MESS) Apple drivers cleanup: [R. Belmont]
- apple3_state is no longer an unnecessary subclass of apple2_state
- ay3600 keyboard decoder is now independent from apple2_state
- cleaned up some includes
restore natural keyboard (nw)
(MESS) apple3: rewrote keyboard handling from scratch using Curt's AY-5-3600 device.  Much, much better. [R. Belmont]
updated documentation [Charles MacDonald]
added missing opcodes and 'illegal opcode'-NMI
(MESS) nes: added support for iNES 2.0 submappers [Fabio Priuli]

out of whatsnew:
+ fixed a small bug in handling MMC-1 games with > 8K of WRAM (only a Jpn baseball games use this, 
   and I can see no difference in behavior)
+ updated emulation status in xml for a few games I had made working during slot-ification
