MDEV-26: Global transaction ID

Adjust full test suite to work with GTID.

Huge patch, mainly due to having to update .result file for all SHOW BINLOG
EVENTS and mysqlbinlog outputs, where the new GTID events pop up.

Everything was painstakingly checked to be still correct and valid .result
file updates.
