dfsound

- Final Fantasy 7 = adsr.c
- use newer PEOPS DSound Sustain level
- PEOPS 1.09a win32 = fix FF7 cursor
 
- freeze.c
- add emu crash check (spu not init yet)
 
- spu.c
- improve spu async timing
- set latency = 20 ms
- smoother, less pops, cracks
 
- spu.c, registers.c
- VAG silence flag (keeps playing channel for IRQs)
- new save states needed
