220.127.116.11: add ATOMIC-DECF, fix WAIT-ON-SEMAPHORE-BUGLET
* We already had SB-EXT:ATOMIC-INCF, so this seems a sensible
companion. I really cannot remember why I didn't do things like
this in the first place -- lack of time, maybe?
* Use ATOMIC-DECF instead of DECF in WAIT-ON-SEMAPHORE to decrement
the waitcount: if we unwind from CONDITION-WAIT due to timeout the
mutex might no longer be ours.
