ayuanx 9eea60ca69 Sound System Rework: Phase 2
. Performance boost
  (Completely non-blocking between Sound thread and CPU thread, in the meantime keeping them thread safe)

. Both 32KHz & 48KHz sound can be handled properly now
  (But up-sampling is still not implemented, and I don't think any game requires it.)

. Strategy adjustment
  When your PC is *NOT* capable to run the game at 100%:
  >> DSound    Could yield more fluent sound than OpenAL sometimes, but you will lose the sync between video & audio (since audio is played before video to guarantee fluency)
  >> OpenAL    Ensures video & audio are always sync'ed, but sound could be intermittent(to let slow video catch up)

. Changed default frame limit to: Auto
  (Somehow this can dramatically decrease the chance of wiimote desync in game NSMB)
