breaks SBR This pre-requisite patch refactors the code for dropping tables, used by DROP TABLE and DROP DATABASE. The patch moves the code for acquiring metadata locks out of mysql_rm_table_part2() and makes it the responsibility of the caller. This in preparation of changing the DROP DATABASE implementation to acquire all metadata locks before any changes are made. mysql_rm_table_part2() is renamed mysql_rm_table_no_locks() to reflect the change.
