Ensure that Annotate_rows is always written direct after GTID information,
before any table_map events.
Before this patch, the following problems existed when mixing
transactional and not transactional tables in the same statement:
- Annotate rows could be written after row events or in the next GTID
event.
- See rpl_row_mixing_engines
- Annotate_rows was not always written to binary log in case of error
with a transactional table (rolled back) but a not transactional
table was updated.
- See sp_trans_log, binlog_row_mix_innodb_myisam
Fixed by writing the Annotate_rows event into the non transactional
cache if there are not transactional tables used. If not, write the
event into the transactional cache.
