  Modified files:
    sys/kern             kern_lock.c 
    sys/sys              lockmgr.h 
  Log:
  - Use a different encoding for lockmgr options: make them encoded by
    bit in order to allow per-bit checks on the options flag, in particular
    in the consumers code [1]
  - Re-enable the check against TDP_DEADLKTREAT as the anti-waiters
    starvation patch allows exclusive waiters to override new shared
    requests.
