WL#1596 "make mysqldump --master-data --single-transaction able to do online dump of InnoDB AND report reliable
binlog coordinates corresponding to the dump".
The good news is that now mysqldump can be used to get an online backup of InnoDB *which works for
point-in-time recovery and replication slave creation*. Formerly, mysqldump --master-data --single-transaction
used to call in fact mysqldump --master-data, so the dump was not an online dump (took big lock all time of dump).
The only lock which is now taken in this patch is at the beginning of the dump: mysqldump does:
FLUSH TABLES WITH READ LOCK; START TRANSACTION WITH CONSISTENT SNAPSHOT; SHOW MASTER STATUS; UNLOCK TABLES;
so the lock time is in fact the time FLUSH TABLES WITH READ LOCK takes to return (can be 0 or very long, if
a table is undergoing a huge update).
I have done some more minor changes listed in the paragraph of mysqldump.c.
WL#2237 "WITH CONSISTENT SNAPSHOT clause for START TRANSACTION":
it's a START TRANSACTION which additionally starts a consistent read on all
capable storage engine (i.e. InnoDB). So, can serve as a replacement for
BEGIN; SELECT * FROM some_innodb_table LIMIT 1; which starts a consistent read too. 

not know there's rollback (if it's because of a dupl row), better warn
that it's happening. It can also be of use for a DBA killing a
connection and wondering what this connection is still doing now. Example:
|  5 | root | localhost | test | Killed  | 10   | Rolling back | insert into i select * from j |

The idea of the fix is that the administrative statements 
OPTIMIZE TABLE, REPAIR TABLE and ANALYZE TABLE should not 
generate binlog errors if there is no errors on the master.
