    sound - Fix default & unit specs for /dev/dsp and /dev/mixer
    
    * /dev/dsp{0,1} was overriding the unit number and forcing the currently
      set default dsp unit, so it didn't matter if you specified /dev/dsp0 or 1,
      it still used hw.snd.default_unit.
    
    * Get rid of the devfs aliasing for /dev/dsp and /dev/mixer.  Instead, use
      the cloner code to lookup the default dsp and default mixer when /dev/dsp
      or /dev/mixer is opened.
    
      This simplifies default handling significantly.
