Description

general LOCK_PROFILING cleanup

only collect timestamps when a lock is contested - this reduces the overhead of collecting profiles from 20x to 5x

remove unused function from subr_lock.c

generalize cnt_hold and cnt_lock statistics to be kept for all locks

NOTE: rwlock profiling generates invalid statistics (and most likely always has) someone familiar with that should review
