jhb 99e2a84a1f Add a new API for soundcards that have hardware volume control: 
- The mixer_hwmute() function can be called when a soundcard receives a
  mute request.
- The mixer_hwstep() function can be used to adjust the volume of one or
  both channels.
- The 'hw.snd.hwvol_step' sysctl determines the amount that mixer_hwstep()
  adjusts the volume by on each call.
- The 'hw.snd.hwvol_mixer' sysctl specifies the mixer device to adjust the
  volume on for both functions.  The values used correspond to the
  SOUNDCARD_MIXER_* constants.
