NES: Test out some savestates, and get more crashes... the problem is that a number of mappers use some state variable names that are identical to APU variable names. Fixed by enclosing entire mapper in a section every time. This particular discovery though, suggests to me that 1.3.0 release NES savestates are possibly much more broken than originally suspected, if mapper IRQ information is being stomped out by APU IRQ information.

The robustness update to the Serializer caused a problem when multiple variables with the same string name are saved\loaded in text form. The old system would just read\write them in order; the new one would silently discard all but the last occurrence. The Serializer now throws an exception in these circumstances. To fix individual cores, duplicate usage of variables needs to be enclosed in separate sections. Fixed an occurrence of this in the NES APU, where the two Pulse channels were being confused; fixes sound bugs on loadstate in some games.

NES: try implementing SEEPROM for BANDAI-FGC boards. Seems to work reading, but I can't get far enough into any of the games for writing. Like the rest of the mapper, only works with crc id because I don't know how to positively identify any of this from ines headers. Affected games:

nes: apu: implement "better" mixing scheme (as recommended by nesdev) in the hope of passing some apu_mixer tests. no change in any of the tests, so change backed out (committed as comments only). from what i understand, it's just as likely that the tests are failing to small channel timing problems as mixer problems.

unify coreinputcomm and coreoutputcomm. there is a slight chance your console will be messed up until i fix a teeny tiny something, since i didnt test them all, since with more recent cores i dunno what roms are working anyway. let me know if i broke anything.

nes: apu: remove unbiasing from apu core. blip_buf already handles a dc bias removal internally, and keeping all of the values to the mixer in their original forms is simpler code and probably reflects the underlying hardware more accurately. should sound about the same as before.

Add Blargg's "blip_buf" as an unmanaged dll. license is LGPL; if I like the way it works, I'll rewrite it with MIT code. Implement it as the new resampling output track for NES. Small (~3%)? speedup. Should sound better, especially when the emulator can't quite keep speed.
