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) 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...
