Modified Files:
        src/sys/dev: audio.c audiovar.h
        src/sys/miscfs/specfs: spec_vnops.c
        src/sys/sys: audioio.h conf.h
        src/usr.bin/audio/ctl: audioctl.1 ctl.c

Log Message:
The audio sub-system now supports the following features as
posted to tech-kern:

    * Simultaneous playback and mixing of multiple streams
    * Playback streams can be of different encoding, frequency, precision
      and number of channels
    * Simultaneous recording to different formats
    * One audio device per process
    * Sysctls to set the common format frequency, precision and channels
    * Independent mixer controls for recording/playback per stream
    * Utilizes little cpu time for multiple streams / good performance
    * Compatible with existing programs that use OSS/NetBSD audio
    * Changes to audioctl(1) to allow specifying process id for corresponding
      audio device
