  Log:
  Various fixups, especially for the upcomming High Definition Audio
  commit.
  
  1) sys/dev/sound/pcm/sound.h
     sys/dev/sound/pcm/channel.c
     * Be more specific: SD_F_SOFTVOL -> SD_F_SOFTPCMVOL
  2) sys/dev/sound/pcm/mixer.[ch]
     * Implement
         mix_setparentchild()
         mix_setrealdev()
         mix_getparent()
         mix_getchild()
       The purpose of these functions is implement relative volume
       adjustment, such as to tie two or more mixer device into a
       single logical device. Usefull for the upcoming HDA driver
       and few AC97 codec (such as AD1981B) where the master volume
       "vol" need to be implemented using this logical manner.
  3) sys/dev/sound/pcm/ac97_patch.[ch]
     * Patch for AD1981B codec to enable (automuting) headphone jack sense.
  4) sys/dev/sound/pcm/ac97.c
     * Implement proper logical master volume for AD9181B codec
       through various mix_set{parentchild,realdev}(). Tie both
       "ogain" (headphone volume) and "phone" (speaker/lineout) to
       a logical "vol".
  5) sys/dev/sound/pcm/usb/uaudio_pcm.c
     * ditto, for "vol" -> { "pcm" }.
