A lot of fixes for prepared statements (PS):

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
