      WL#2868 Fix backup trigger handling · d88e5766
      stewart@mysql.com authored
      BACKUP previous set up triggers using DICT.
      This lead to all kind of trouble.
      An smaller alternative to using SUMA for backup
        is to just make BACKUP handle triggers to TUP directly.
      
      This way all triggers will be totally local,
        and error handling is much simpler.
      
      --- old impl.
      
      Start: Master recives GSN_DEFINE_BACKUP_CONF from all participants
      Master sends CREATE_TRIG_REQ for all tables to local DICT (dict master)
      Master sends START_BACKUP_REQ to all paricipants with trigger ids from DICT
      Master sends ALTER_TRIG_REQ (online) to local DICT
      Master waits for GCP
      Master starts distributed scan
      When scan has finished
      Master waits for GCP
      Master sends DROP_TRIGGER to local DICT
      Master sends STOP_BACKUP_REQ to all participants
      
      --- new impl.
      
      Start: Master recives GSN_DEFINE_BACKUP_CONF from all participants
      Master sends START_BACKUP_REQ to all paricipants
        Participand sends CREATE_TRIG_REQ for all tables to local TUP
      Master waits for GCP
      Master starts distributed scan
      When scan has finished
      Master waits for GCP
      Master sends STOP_BACKUP_REQ to all participants
        Participant sends DROP_TRIGGER to local TUP
      
      Changes:
      All trigger handling is _local_
       This implies, that abort (e.g due to node failure) can be _local_
      
      
      fix testBackup test so that it will run successfully with the (now correct)
      backup trigger code.
