In Item_ref::Item_ref set maybe_null (and other fields fix_fields sets) to be the 
same as in (*ref), because Item_ref::fix_fields() will not be called.  Previously 
maybe_null was 0 always and this produced a bogus state where 
maybe_null==0 && is_null() == true 
which broke evaluation for some upper-level Items, like AND and OR.

insertion of new records partially failed. It would get logged because of the
logic to log a partially-failed 'INSERT ... SELECT' (which can't be rolled back
in non-transactional tables), but 'CREATE TABLE ... SELECT' is always rolled
back on failure, even for non-transactional tables. (Bug #6682)
(Original fix reimplemented after review by Serg and Guilhem.)

two-line fix for BUG#6732 "FLUSH TABLES WITH READ LOCK + COMMIT makes next FLUSH...LOCK hang forever"
(originally reported as "second run of innobackup hangs forever and can even hang server").
Plus testcase for the bugfix and comments about global read locks.

When mysqlbinlog prints LOAD DATA INFILE, let it print the thread id. Some customer would have benefited
much from this in his recovery. All this change does is adding one commented (#) line before the LOAD DATA
command, so it is quite innocuous.

  Fix InnoDB bug #6287: if one uses INSERT IGNORE to insert several rows at a time, and the first inserts are ignored because of a duplicate key collision, then InnoDB in a replication slave assigns AUTO_INCREMENT values 1 bigger than in the master

When we are writing a transaction to the binlog, we log BEGIN/COMMIT with zero error code.
Example: all statements of trans succeeded, connection lost and so implicit rollback:
we don't want ER_NET* errors to be logged in the BEGIN/ROLLBACK events, while statement
events have 0. If there was really a serious error code, it's already in the statement events.

Revise the --hex-blob help message string. (This will need
