bmove_allign -> bmove_align Added OLAP function ROLLUP Split mysql_fix_privilege_tables to a script and a .sql data file Added new (MEMROOT*) functions to avoid calling current_thd() when creating some common objects. Added table_alias_charset, for easier --lower-case-table-name handling Better SQL_MODE handling (Setting complex options also sets sub options) New (faster) assembler string functions for x86
