r20919: add a function cluster_tdb_tmp_open() which can be used in a cluster environment for subsystems that have not yet been converted to use ctdb to get a shared temporary tdb (This used to be commit 0ed91384497aed6817b2220c31344bfcd45fd033)

r21230: added the hooks needed in the cluster layer and the messaging code for handling messages to remote nodes. Implemented dummy functions in the 'local' cluster backend for the messaging hooks, and modified the messaging layer to check if the destination is remote and redirect messages via the cluster layer (This used to be commit 4474552e8fb73efebef32ad8480d7fe9a1e379ef)
