MDEV-26: Global transaction ID.

Browse Source 
Replace CHANGE MASTER TO ... master_gtid_pos='xxx' with a new system
variable @@global.gtid_pos.

This is more logical; @@gtid_pos is global, not per-master, and it is not
affected by RESET SLAVE.

Also rename master_gtid_pos=AUTO to master_use_gtid=1, which again is more
logical.
