More fixes for 8.4 DTrace probes. Remove useless BUFFER_HIT/BUFFER_MISS
probes --- the BUFFER_READ_DONE probe provides the same information and more
besides. Expand the LOCK_WAIT_START/DONE probe arguments so that there's
actually some chance of telling what is being waited for. Update and
clean up the documentation.
