- Remove witness_dead and just use witness_watch instead.  If witness_watch   is set to 0, it now has the same affect as setting witness_dead used to   have. - Added a sysctl handler that allows root to change witness_watch from a   non-zero value to zero to disable witness at runtime.  Note that you   can't turn witness back on once it is off.  You can only turn it off as   a one-way switch. - Added a comment describing the possible values of witness_watch.
