s3:dbwrap_ctdb: start rewrite of transactions using the global lock (g_lock)
This simplifies the transaction code a lot: * transaction_start essentially consists of acquiring a global lock. * No write operations at all are performed on the local database until the transaction is committed: Every store operation is just going into the marshall buffer. * The commit operation calls a new simplified TRANS3_COMMIT control in ctdb which rolls out thae changes to all nodes including the node that is performing the transaction.
