This commit makes replicas crash-safe by default by changing the Using_Gtid value to be Slave_Pos on a fresh slave start and after RESET SLAVE is issued. If the primary server does not support GTIDs (i.e., version < 10), the replica will fall back to Using_Gtid=No on slave start and after RESET SLAVE. The following additional informational messages/warnings are added: 1. When Using_Gtid is automatically changed. That is, if RESET SLAVE reverts Using_Gtid back to Slave_Pos, or Using_Gtid is inferred to No from a CHANGE MASTER TO given with log coordinates without MASTER_USE_GTID. 2. If options are ignored in CHANGE MASTER TO. If CHANGE MASTER TO is given with log coordinates, yet also specifies MASTER_USE_GTID=Slave_Pos, a warning message is given that the log coordinate options are ignored. Additionally, an MTR macro has been added for RESET SLAVE, reset_slave.inc, which provides modes/options for resetting a slave in log coordinate or gtid modes. When in log coordinates mode, the macro will execute CHANGE MASTER TO MASTER_USE_GTID=No after the RESET SLAVE command. When in GTID mode, an extra parameter, reset_slave_keep_gtid_state, can be set to reset or preserve the value of gtid_slave_pos. Reviewed By: =========== Andrei Elkin <andrei.elkin@mariadb.com>
