is possible):
When skipping the beginning of a transaction starting with BEGIN, the OPTION_BEGIN
flag was not set correctly, which caused the slave to not recognize that it was
inside a group. This patch sets the OPTION_BEGIN flag for BEGIN, COMMIT, ROLLBACK,
and XID events. It also adds checks if inside a group before decreasing the
slave skip counter to zero.
Begin_query_log_event was not marked that it could not end a group, which is now
corrected.
Fixing tests and results to work when replicating to fewer columns on
slave than on master. One test that previously should fail, now works,
and some log positions have changed as a result of adding metadata to
the events.
