  Modified files:
    sys/dev/sound/pcm    datatypes.h mixer.c mixer.h sound.c 
  Log:
  - Make the 'hwvol_mixer' and 'hwvol_step' variables be specific to a
    specific snd_mixer device rather than global across all mixers.
  - Add per-mixer mute status and saved mute_level so that the mixer_hwmute()
    function can now toggle the mute state when the mute button is pressed.
  - Create a dynamic sysctl tree hw.snd.pcmX when a pcm device is registered.
  - Move the hw.snd.hwvol_* sysctl's to hw.snd.pcmX.hwvol_* so that they
    are now properly device-specific.  Eventually when the mixers become
    their own devices these sysctl's will move to live under a mixerX tree.
  - Change the interface of the hwvol_mixer sysctl so that it reports the
    name of the current mixer device instead of the number and is settable
    with the name instead of the number.
  - Add a new function mixer_hwinit() used to setup the dynamic sysctl's
    needed for the hwvol support that can be called by drivers that support
    hwvol.
