snes: Fix rewind issue with tales of phantasia. Full details are as follows: Synchronize events occur right BEFORE the original thread tries to modify the data. That means that if, for instance, the SMP thread switches off to the CPU thread for a synchronize, but then the CPU switches to the PPU, commits a frame, and then in runtosave, finalizes, without having ever advanced past the SMP, when the SMP runs to save, it will do a data modify without being properly synced. The solution is for the CPU to not stop in runtosave until there's enough time for both the PPU and SMP to finish. Because of our stateful design, there's at most one event pending, so that simplifies to (smp.clock < 0 && ppu.clock < 0). This is unfortunately never guaranteed to finish, but with short timing segments on stateful PPU and SMP, and special guards in the PPU and SMP to switch back to the CPU as quickly as possible when in runtosave, it seems to work out.

snes: ppu: state out similarly to apu. this was a very simple project; unlike the apu, there aren't many sync points. like the apu, a message is dumped to the console if runtosave causes determinism problems. like the apu, there's no speed hit, but tales of phantasia is still broken. breaks savesates.

snes-refactor bsnes bindings to work via external process. should solve all stability problems. there is much sloppy transitionary code still in this commit; we need to smoke out any killer issues with this approach before committing too heavily. speed is close enough to last release, and can still be improved.

bsneshawk step 1 of N - compile libsnes, make bsneshawk core, setup interop, support frameadvance, video, gamepad. games are playable, I think.
