Bug #2304 HANDLER does not retain database name with table aliases

Description:
Cross-database HANDLER statements do not retain the database name when resolving a table alias.  This does not appear to be documented.

How to repeat:
USE test;
CREATE TABLE hdlr ( a int primary key );
USE mysql;
HANDLER test.hdlr OPEN AS halias;
HANDLER halias READ `PRIMARY` FIRST;
HANDLER test.halias READ `PRIMARY` FIRST;
USE test;
HANDLER halias READ `PRIMARY` FIRST;
HANDLER halias CLOSE;
DROP TABLE hdlr;

Suggested fix:
Retaining the database is preferable; otherwise, document it.

Doing a "use database;" will also trigger this problem.

mysql> use CFS;
Database changed
mysql> handler XDSYN open as A3;
Query OK, 0 rows affected (0.00 sec)
mysql> use DAVG;
Database changed
mysql> handler A3 read key01 first;
ERROR 1109: Unknown table 'A3' in HANDLER
mysql> use CFS;
Database changed
mysql> handler A3 read key01 first;
<successful>
