      Apply the following InnoDB snapshots:
      innodb-5.0-ss1319
      innodb-5.0-ss1331
      innodb-5.0-ss1333
      innodb-5.0-ss1341
      
      Fixes:
      - Bug #21409: Incorrect result returned when in READ-COMMITTED with query_cache ON
        At low transaction isolation levels we let each consistent read set
        its own snapshot.
      - Bug #23666: strange Innodb_row_lock_time_% values in show status; also millisecs wrong
        On Windows ut_usectime returns secs and usecs relative to the UNIX
        epoch (which is Jan, 1 1970).
      
      - Bug #25494: LATEST DEADLOCK INFORMATION is not always cleared
        lock_deadlock_recursive(): When the search depth or length is exceeded,
        rewind lock_latest_err_file and display the two transactions at the
        point of aborting the search.
      
      - Bug #25927: Foreign key with ON DELETE SET NULL on NOT NULL can crash server
        Prevent ALTER TABLE ... MODIFY ... NOT NULL on columns for which
        there is a foreign key constraint ON ... SET NULL.
      
      - Bug #26835: Repeatable corruption of utf8-enabled tables inside InnoDB
        The bug could be reproduced as follows:
      
        Define a table so that the first column of the clustered index is
        a VARCHAR or a UTF-8 CHAR in a collation where sequences of bytes
        of differing length are considered equivalent.
      
        Insert and delete a record.  Before the delete-marked record is
        purged, insert another record whose first column is of different
        length but equivalent to the first record.  Under certain conditions,
        the insertion can be incorrectly performed as update-in-place.
      
        Likewise, an operation that could be done as update-in-place can
        unnecessarily be performed as delete and insert, but that would not
        cause corruption but merely degraded performance.
