NES - make mappers and whatnot sealed classes, since it may theoretically be a tiny speedup, and if nothing else, it is more conceptually correct

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: apu: add some pulse channel variables to the savestate that weren't in it before. maybe this fixes something? maybe it doesn't. it certainly doesn't fix my problem in driar...

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.

VRC6 audio: restructure to send deltas directly to the NES apu, simplifying some things. This would be pointless masturbation by itself, but this method will also lead to easier emulation of MMC5 audio.

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.

nes-fix dmc sfx bug in bt&dd making nonexistent sfx; add emulation of empty databus (to extra joystick bits and reads of nonexistent EXP and WRAM memory ranges.. need to scan other emulator source codes for places to check for use of empty databus); fixes freeze bug in bt&dd. also break savestates, but add a crude version system so we at least have a way to avoid it in the future.
...
bt&dd has a glitch that reads from $6000 when there is no ram installed, and crashes if something too large is returned. I think this chooses a frame for abobo, and you can actually see abobo's sprites glitch for one frame right when the wall finishes getting busted down (the same place where bizhawk was freezing)

i implemented dwedit's DMC fix as best as i could understand it. 'Fire Hawk (USA) (Unl).nes' no longer has graphical glitches on the intro screen.
...
audio still sounds wrong, and crash still occurs once you get in game

general cleanup.. remove a bunch of warnings.. improve log console system a bit.. add new icons for log console window.. remove old demo psx interop system and add new, simpler one, which isnt really tested yet but is way less annoying.

Max volume is settable per sound source to enable mixing many sound sources without clipping. Potentially can be used to disable individual sound sources.
