MDEV-26. Intermediate commit.

Implement binlog_gtid_pos() function. This will be used so that
the slave can obtain the gtid position automatically from first
connect with old-style position - then MASTER_GTID_POS=AUTO will
work the next time. Can also be used by mysqldump --master-data
to give the current gtid position directly.
