Functionality added or changed:
          Added MAXLOCKS,
          MINLOCKS, MAXWRITE, and
          MINWRITE as allowable values of the
          --bdb-lock-detect option. (Bug#14876)
        
          Added the bdb_cache_parts and
          bdb_region_size system variables, and
          allowed bdb_cache_size to be larger than
          4GB on systems that support it. (Bug#14895)
        
          Added Transactions, XA,
          and Savepoints columns to SHOW
          ENGINES output.
        
          Added --replace to
          mysqldump. This option uses
          REPLACE INTO, rather than INSERT
          INTO, when writing the dumpfile.
        
Bugs fixed:
          Foreign keys were not properly enforced in
          TEMPORARY tables. Foreign keys now are
          disallowed in TEMPORARY tables. (Bug#12084)
