      Bug #27417 thd->no_trans_update.stmt lost value inside of SF-exec-stack
        
      Once had been set the flag might later got reset inside of a stored routine 
      execution stack.
      The reason was in that there was no check if a new statement started at time 
      of resetting.
      The artifact affects most of binlogable DML queries. Notice, that multi-update 
      is wrapped up within
        bug@27716 fix, multi-delete bug@29136.
        
      Fixed with saving parent's statement flag of whether the statement modified 
      non-transactional table, and unioning (merging) the value with that was gained 
      in mysql_execute_command.
        
      Resettling thd->no_trans_update members into thd->transaction.`member`;
      Asserting code;
      Effectively the following properties are held.
        
      1. At the end of a substatement thd->transaction.stmt.modified_non_trans_table
         reflects the fact if such a table got modified by the substatement.
         That also respects THD::really_abort_on_warnin() requirements.
      2. Eventually thd->transaction.stmt.modified_non_trans_table will be computed as
         the union of the values of all invoked sub-statements.
         That fixes this bug#27417;
      
      Computing of thd->transaction.all.modified_non_trans_table is refined to base to 
      the stmt's value for all the case including insert .. select statement which 
      before the patch had an extra issue bug@28960.
      Minor issues are covered with mysql_load, mysql_delete, and binloggin of insert in
      to temp_table select. 
        
      The supplied test verifies limitely, mostly asserts. The ultimate testing is defered
      for bug@13270, bug@23333.

      Bug#25679 · fbcd70a4
        "Federated Denial of Service"
        Federated storage engine used to attempt to open connections within
        the ::create() and ::open() methods which are invoked while LOCK_open
        mutex is being held by mysqld. As a result, no other client sessions
        can open tables while Federated is attempting to open a connection.
        Long DNS lookup times would stall mysqld's operation and a rogue
        connection string which connects to a remote server which simply
        stalls during handshake can stall mysqld for a much longer period of
        time.
        This patch moves the opening of the connection much later, when the
        federated actually issues queries, by which time the LOCK_open mutex is
        no longer being held.
