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.

overhaul the dbri driver and make it work again in the New Order Of Things
- fix switching between control and data mode
- make sure interrupts can happen in control mode
- implement audioif.commit_settings()
- switch to control mode only if needed - for changes in sample rate or format
  but not for things like volume control
should fix PR 52786

fix several KASSERT()s and locking in a few places.

fixes DIAGNOSTIC kernels and still plays.
