dae4f53acb clvmd: add mutex protection for cpg_ call
The library for corosync multicasting is not supporting multithread
usage - add local mutex to avoid parallel call of cpg_mcast_joined().

bf19c6be2c cleanup: clvmd move destroy_lvhash into main
Keep destruction code path consistent and simple and
destroy lvhash in the place it's been created.
Also issue debug message from a single place.

431eda63cc clvmd: Fix node up/down handing in corosync module
The corosync cluster interface for clvmd did not correctly
deal with node up/down events so that when a node was removed
from the cluster clvmd would prevent remote operations
from happening, as it thought the node was up but not
running clvmd.

This patch fixes that code by simplifying the case to node
being  up or down - which was the original intention
and is supported by pacemaker and CPG in the higher layers.

90d106ef19 Restart CLVMD with same cluster manager
Add named cluster_ops to easily learn the name of the active cluster manager,
so we are able to restart singlenode manager in testing.

Add simple test for clvmd -S  (restart) and -R (refresh)
(though it needs some extensions).

679830cf58 In some versions (RHEL6) dlm_create_lockspace() always
return lockspace reference (even if lockspace already exists)
and thus increases DLM lockspace count. It means that after
clvmd restart the lockspace is still in use.

(The only way to clean environment to enable clean cluster
shutdown is call "dlm_tool leave clvmd" several times.)

Because only one clvmd can run in time, we can use simpler logic,
try to open lockspace with dlm_open_lockspace() and only if it fails
try to create new one. This way the lockspace reference doesn not
increase.

Very easily reproducible with  "clvmd -S" command.

Patch also fixes return code when clvmd_restart fails and fixes
double free if debug option was specified during restart.

c4ff133840 Tidy lv_hash[_lock] use inside clvmd.
- Rename unlock_all to destroy_lvhash,
this function is called in cluster shutdown
unlocks everything and clean up allocated info space.

 - Tidy lv_hash_lock use
.
Except adding free(lvi) in lv_has destructror
there is no functional change.
