attempted to keep the MariaDB testcases, unfortunately without

perspective the difference in the implementations was the following:
http://bugs.mysql.com/bug.php?id=68932 (IMHO serious)
http://bugs.mysql.com/bug.php?id=68953 (IMHO serious, fixed in 5.6.12).
The fact that we didn't port all the testcases is
