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.

Fix vgsplit locking and remove unneeded error messages when split into new VG.
When vg_lock_and_read() calls were added, they were done so incorrectly for
the destination VG (vg_to). This resulted in the VG lock not obtained when
a new VG was the destination (vg_lock_and_read() would fail in the vg_read()
clause, which would then release the lock before returning NULL), and could
result in corrupted destination VG.
The fix was to put back the original lock_vol() and vg_read() calls for 'vg_to'.
The failure of vg_read() indicates "vg does not exist", and we key off that
to determine whether we are dealing with a new or existing VG as the
destination.
The first two error messages were also the result of the incorrect
vg_lock_and_read() calls:
Volume group "new" not found
cluster request failed: Invalid argument
New volume group "new" successfully split from "vg"
