Fixed a problem from 3.23.17 when choosing character set on the client side.
            Added FLUSH TABLES WITH READ LOCK to make
            a global lock suitable for making a copy of MySQL datafiles.
          
            CREATE TABLE ... SELECT ... PROCEDURE now
            works.
          
            Internal temporary tables will now use compressed index when
            using GROUP BY on
            VARCHAR/CHAR columns.
          
            Fixed a problem when locking the same table with both a
            READ and a WRITE lock.
          
            Fixed problem with myisamchk and
            RAID tables.
