bunch of bugs when external_lock() fails on unlock: * mi_lock_database() used mi_mark_crashed() under share->intern_lock, but mi_mark_crashed() itself locks this mutex. * handler::close() required table to be unlocked, but failed external_lock didn't count as unlock * mysql_unlock_tables() ignored all unlock errors, but they still set the error status in stmt_da.
