WL#518: Binary logs transaction IDs, Flush before commit
In order to guarantie correct binary log state for systems which need corectness we should do the followings 1) Add transaction IDs to COMMIT/AUTOCOMMIT=1 messages in BINARY log 2) Add possibility to do fsync/fflush binary log at transaction commit to be done before INNODB transaction commit. So there would ne no chance transactions are lost in binary log. 3) At recovery stage INNODB should have an option to cut not commited transaction from the end of binary log.
