  Modified files:
    sys/kern             kern_lock.c subr_witness.c 
  Log:
  - Re-introduce WITNESS support for lockmgr.  About the old implementation
    the only one difference is that lockmgr*() functions now accept
    LK_NOWITNESS flag which skips ordering for the instanced calling.
  - Remove an unuseful stub in witness_checkorder() (because the above check
    doesn't allow ever happening) and allow witness_upgrade() to accept
    non-try operation too.
