A lot of fixes for prepared statements (PS):

Browse Source 
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


BitKeeper/deleted/.del-innodb-lock-master.opt~f76a4a1999728f87:
  Delete: mysql-test/t/innodb-lock-master.opt
client/Makefile.am:
  mysqltest now uses regex
client/mysqltest.c:
  Added support for testing of prepared statements (with --ps-protocol)
  Main code was done by Kent, I did mainly some cleanups and minor bug fixes
  New test commands:
  --disable_ps_protocol
  --enable_ps_protocol
  NOTE: new code still has some things that needs to be cleaned up.
  For example run_query_stmt_handle_error() should be made more general so that same code can be used also by 'normal' queries
configure.in:
  mysqltest now uses regex
libmysql/libmysql.c:
  Reset warning_count after prepare (safety). In the future we should also provide warnings on prepare
  integer -> string conversion now handles ZEROFILL
  double -> string conversion is now closer to the one in the server
  Fixed crash when one called mysql_stmt_store_result() without preceding mysql_stmt_bind_result()
