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