unknown 157002b12f WL#3270 "Maria - cleanups of inherited MyISAM functionality" 
Removing the "external lock" functionality from Maria (as two separate processes wanting to share a table
should not only my_lock() the data and index files but also the log files, and share memory
(as the latest data is in the page cache), it sounds useless to feature this).
Removing the MyISAM logging from Maria (as REDO logging will be done differently).
