Fixed 8-bit WAV format handling (it is unsigned data).
Fixed off-by-one checks for buffer wrap. Increment ref count for primary buffer in CreateSoundBuffer(). Added DSBPN_OFFSETSTOP support to position notification code. Lots of minor parameter validation checks. Stubs for: IDirectSound_initialize(), IDirectSound_Compact(), and IDirectSound_GetSpeakerConfig(). Fixed freq shifting with 16-bit data problem, fixed 8bit<->16bit conversion. Lots of thread locking for DirectSound buffers. Dealloc primary buffer when dsound is deallocated.
