Modified Files:
        src/sys/dev/sbus: dbri.c dbrivar.h

Log Message:
fix audiomp bugs:
- switch from tsleep/wakeup to condvar
- fix locking in a bunch of places.  there were several locking
  against myself issues.

also:
- don't let dbri_process_interrupt_buffer() loop more than once
  over the array of intrs.

this fixes hangs when using audio on ss20 in -current, but does
not make audio work.  it eventually times out with eg:

dbri0: switching to control mode timed out (0 f6)

and may leave a sample in the audio buffer repeating.
