Change of user interface to be more logical and more in line with expectations to work similar to old-style replication. User can now explicitly choose in CHANGE MASTER whether binlog position is taken into account (master_gtid_pos=current_pos) or not (master_gtid_pos= slave_pos) when slave connects to master. @@gtid_pos is replaced by three separate variables @@gtid_slave_pos (can be set by user, replicated GTIDs only), @@gtid_binlog_pos (read only), and @@gtid_current_pos (a combination of the two, most recent GTID within each domain). mysql.rpl_slave_state is renamed to mysql.gtid_slave_pos to match. This fixes MDEV-4474.
