David Teigland 91c0dc93a1 [DLM] fix aborted recovery during node removal
Red Hat BZ 211914

With the new cluster infrastructure, dlm recovery for a node removal can
be aborted and restarted for a node addition.  When this happens, the
restarted recovery isn't aware that it's doing recovery for the earlier
removal as well as the addition.  So, it then skips the recovery steps
only required when nodes are removed.  This can result in locks not being
purged for failed/removed nodes.  The fix is to check for removed nodes
for which recovery has not been completed at the start of a new recovery
sequence.

To aid debugging, it's useful to be able to see what nodeid the dlm is
waiting on for a message reply.

David Teigland f6db1b8e72 [DLM] abort recovery more quickly
When we abort one recovery to do another, break out of the ping_members()
routine more quickly, and wake up the dlm_recoverd thread more quickly
instead of waiting for it to time out.

David Teigland e7fd41792f [DLM] The core of the DLM for GFS2/CLVM
This is the core of the distributed lock manager which is required
to use GFS2 as a cluster filesystem. It is also used by CLVM and
can be used as a standalone lock manager independantly of either
of these two projects.

It implements VAX-style locking modes.
