LP:697597 - HANDLER + Aria asserts in maria-5.3-handler

Handler operations are altogether broken with Aria in maria-5.3-handler. They assert as follows:

mysqld: ha_maria.cc:2783: virtual THR_LOCK_DATA** ha_maria::store_lock(THD*, THR_LOCK_DATA**, thr_lock_type): Assertion `lock_type != TL_UNLOCK && (lock_type == TL_IGNORE || file->lock.type == TL_UNLOCK)' failed.

backtrace:

test case:

CREATE TABLE t1 ( f1 integer ) engine=aria;
HANDLER t1 OPEN;
HANDLER t1 CLOSE;
HANDLER t1 OPEN;

Furthermore, there seem to be no tests for Aria + HANDLER in the test suite. There are handler_myisam and handler_innodb tests only.
