  Modified files:
    sys/dev/sound/pcm    mixer.c mixer.h 
  Log:
  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.
