Subject: 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)
