Bug #13231 mysqltest: fails to dectect when mysql_next_result fails 

 - Added functionality to check errors returned from mysql_next_result
 - Exit from mysqltest when and unexpected error occurs.
 - The above fixes reveal problems with rpl000009, sp-error and query_cache-
 - Fix sp-error by adding an expected error
 - Fix rpl000009 by not sending "ok" from mysql_create_db when called with silent flag from load_master_data
 - Fix query_cache in separate patch


client/mysqltest.c:
  Check and handle error after mysql_next_result
  Change several verbose_msg to die so that the error is properly reported
  Clean up of error handling code in run_query_stmt, check all errors and use common
  function handle_error.
mysql-test/r/mysqltest.result:
  mysqltest now dies when a query fails with wrong errno
mysql-test/r/sp-error.result:
  Update test result to match the expected error from calling the sp closing a cursor that is not open.
mysql-test/t/sp-error.test:
  Add missing --error 1326 before call to sp that closes a already closed cursor.
  Add test for bug9367
sql/sql_db.cc:
  Don't send ok in mysql_create_db if silent flag is set.
