Release 4.5: Replication method naming

The method names DB_ENV->set_rep_limit, DB_ENV->get_rep_limit and DB_ENV->set_rep_transport have been changed to DB_ENV->rep_set_limit(), DB_ENV->rep_get_limit() and DB_ENV->rep_set_transport() in order to be consistent with the other replication method names. That is, the characters "set_rep" and "get_rep" have been changed to "rep_set" and "rep_get".

Applications should modify the method names, no other change is required.
