Redesigned the handler close functions so that they are usable at different places where waiting for closing tables is done. mysql-test/r/flush_table.result: bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock. Added the test results. mysql-test/t/flush_table.test: bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock. Activated old test case. Added new test cases. sql/mysql_priv.h: bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock. Made mysql_ha_close() more flexible. Removed mysql_ha_closeall(), which closed only one table despite its name. Added mysql_ha_close_list(), which closes the complete list or all tables and does not lock. Removed a duplicate declaration. sql/sql_base.cc: bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock. Added proper close calls before some wait points to avoid deadlocks or infinite loops. sql/sql_handler.cc: bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock. Redesigned the internal function find_table_ptr_by_name(). It can now suppress locking and tells if the requested table has been flushed by itself. Extended mysql_ha_close() so that it can now suppres locking and error reporting. That way it can be used at more places and the old function mysql_ha_closeall() is now obsolete. Added a new function mysql_ha_close_list() which closes a whole list of HANDLER tables or all HANDLER tables, if the list is NULL. Furthermore is can close all 'old' (marked for flush) HANDLER tables. sql/sql_table.cc: bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock. Replaced the obsolte mysql_ha_closeall() by the new mysql_ha_close().
