  Modified files:
    sys/dev/sound/pcm    vchan.c sound.c sound.h 
  Log:
  don't flag the playback hardchan as busy on devices with only one of them.
  
  if a device has vchans already but they are all busy, allocate another one
  at open() time, up to a maximum of hw.snd.maxvchans.
  
  when creating/destroying vchans, don't make/remove a devnode for the
  first/last one as it replaces a hardchan.
