[DLM] add orphan purging code (1/2)
Add code for purging orphan locks. A process can also purge all of its own non-orphan locks by passing a pid of zero. Code already exists for processes to create persistent locks that become orphans when the process exits, but the complimentary capability for another process to then purge these orphans has been missing.
