  Modified files:
    sys/sys              _mutex.h 
    sys/kern             kern_mutex.c 
  Log:
  Instead of get_cyclecount(9), use nanotime(9) to record acquisition and
  release times.  Measurements are made and stored in nanoseconds but
  presented in microseconds, which should be sufficient for the locks for
  which we actually want this (those that are held long and / or often).
  Also, rename some variables and structure members to unit-agnostic names.
