[Alexander Nozdrin]

 3469 Alexander Nozdrin	2010-12-22
      A patch for Bug#59022 (Valgrind warning in write_delayed() after InnoDB merge).
      
      Fix memory leak introduced by WL#5092 'RBR: Options for writing

      Free memory which is allocated for column bitmap associated with
      each row to be processed by delayed insert handler thread.

      BUG#59079 rpl_binlog_errors.test fails when enables binlog-checksum
      
      The test case dependent on the size of incident event to calculate
      the event offset, howerver, the size of Incident_log_event is different when binlog-checksum
      is enabled, and caused the test case to fail.
      
      Fixed the problem by use the event sequence number instead event
      log file position to locate the incident event.
