Fix snapshot monitoring library to not cancel monitoring invalid snapshot.
...
snapshot DSO unregistered itself when snapshot changed state to invalid.
This can cause a race (and several timeouts), when for example another snapshot
is added and in the middle of operation (suspend/resume) the monitoring thread
unregister itself.
Fix it by keeping the snapshot monitored after invalidation - just reset
threshold to not really print any messages to syslog.

Fix dmeventd regression where mirror and snapshot monitoring libraries
...
failed to link against liblvm2cmd.
Dmeventd DSOs *require* lvm2cmd to be linked in.
For the future:
1) AC_SUBST does not create Makefile variables, only @foo@-style substitutions
2) When using `test', whitespace around `=' is essential:
test a=b is true, as is test a=a

The attached patch is a try to make clvmd work correctly on openais stack.
...
It does 2 things.
1. The cpg_deliver_callback make a compare between target_nodeid and our_nodeid.
It turns out openais set target_nodeid to 0 sometimes. for broadcasting ? I change the behavior so that lvm will process_remote also on target_nodeid == 0
2. The joined_list passed to cpg_confchg_callback doesn't include the already exist nodes in the group, which leads to an incomplete node_hash. I simply add all other nodes in member_list to node_hash also.
Thanks to Xinwei Hu for this patch.
