WL#5370 Keep forward-compatibility when changing
'CREATE TABLE IF NOT EXISTS ... SELECT' behaviour BUG#55474, BUG#55499, BUG#55598, BUG#55616 and BUG#55777 are fixed in this patch too. This is the 5.1 part. It implements: - if the table exists, binlog two events: CREATE TABLE IF NOT EXISTS and INSERT ... SELECT - Insert nothing and binlog nothing on master if the existing object is a view. It only generates a warning that table already exists.
