  - Make witness_watch a 3 state value.
    1 means that witness is up and running.
    0 means that witness is disabled but that it can be established later
      again in effective way.
    -1 means that witness is disabled permanently
  - Fix a bug causing kernel to panic on witness disabling through
    witness_watch.  lock lists queues were still full of entries and this was
    causing throubles with debugging stubs (like witness_thread_exit()).
