Release 4.5: Replication events

One of the informational returns from the DB_ENV->rep_process_message() method found in previous releases of Berkeley DB has been changed to an event. The DB_REP_STARTUPDONE return from DB_ENV->rep_process_message() is now the DB_EVENT_REP_STARTUPDONE value to the DB_ENV->set_event_notify() callback.

Applications should update their handling of this event as necessary.
