Alexander Leidinger 28ef3fb011 sys/dev/sound/pcm/sndstat.c:
* General spl* cleanup. It doesn't serve any purpose anymore.
   * Nuke sndstat_busy(). Addition of sndstat_acquire() /
     sndstat_release() for sndstat exclusive access. [1]

sys/dev/sound/pcm/sound.c:
   * Remove duplicate SLIST_INIT()
   * Use sndstat_acquire() / release() to lock / release the entire
     sndstat during pcm_unregister(). This should fix LOR #159 [1]

sys/dev/sound/pcm/sound.h:
   * Definition of SD_F_SOFTVOL (part of feeder volume)
   * Nuke sndstat_busy(). Addition of sndstat_acquire() /
     sndstat_release() for exclusive sndstat access. [1]
