82924a36bf 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

a0e3e3912d rename struct write_info as struct track_info, and the variable name 'wi' 
as 'ti', as this info is useful for reading as well.

3a70beec89 separate the 3 functions midirecord uses from libaudio.a into its own 
file and link it directly, instead of having an (implicit) dependancy
on usr.bin/audio/common being built before usr.bin/midirecord is linked.

0c2e06460b move most of the header writing code from record.c into wav.c and sun.c. 
introduce a struct write_info for communication between front ends and
backends.

libaudio API is still pretty ugly, and needs to stay local here for now,
but it is a little more usable for other tools now.

906f130f1a check that an output file is given before doing any other work.
