replication): Patch to add binlog format capabilities to the InnoDB storage engine. The engine will not allow statement format logging when in READ COMMITTED or READ UNCOMMITTED transaction isolation level. In addition, an error is generated when trying to use READ COMMITTED or READ UNCOMMITTED transaction isolation level in STATEMENT binlog mode.
