  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 where the master volume "vol" need to be
       implemented using this logical manner.
  3) sys/dev/sound/pcm/ac97.c
     * ditto #1
     sys/dev/sound/pcm/usb/uaudio_pcm.c
     * ditto #1, hook "pcm" as logical child of "vol" if the real
       control does not exist.
