New mysqltest that can run mysqltest with PS Added support for ZEROFILL in PS Fixed crash when one called mysql_stmt_store_result() without a preceding mysql_stmt_bind_result() Updated test cases to support --ps-protocol (Some tests are still run using old protocol) Fixed crash in PS when using SELECT * FROM t1 NATURAL JOIN t2... Fixed crash in PS when using sub queries Create table didn't signal when table was created. This could cause a "DROP TABLE created_table" in another thread to wait "forever" Fixed wrong permissions check in PS and multi-table updates (one could get permission denied for legal quries) Fix for PS and SELECT ... PROCEDURE Reset all warnings when executing a new PS query group_concat(...ORDER BY) didn't work with PS Fixed problem with test suite when not using innodb
