    From Volker:
    
    This fixes the following condition: On a cluster with many nodes a single
    node
    was running as the only node. Any transaction that was attempted against the
    persistent databases hung. From a former run of the cluster
    "__transaction_lock__" existed in the persistent databases, but with a dmaster
    entry in the ctdb header that was not the local node. When the
    transaction_start code tried to acquire this, ctdb queued the dmaster request
    to a node that does not exist, hanging forever.
    
    I though -- wait a second, why has nobody found this yet with non-persistent
    databases? Answer: Non-persistent databases are opened with CLEAR_IF_FIRST,
    which means that all records are locally deleted when ctdb attaches to it.
    
    This wipe does not happen for persistent databases, but we have this one
    __transaction_lock__ record around that is treated like a non-persistent
    database. This patch treats the __transaction_lock__ for persistent db's
    specially: It deletes it locally when ctdbd attaches to the db.
