MDEV-4506: Parallel replication: Intermediate commit.
Fix some part of update of old-style coordinates in parallel replication: - Ignore XtraDB request for old-style coordinates, not meaningful for parallel replication (must use GTID to get crash-safe parallel slave). - Only update relay log coordinates forward, not backwards, to ensure that parallel threads do not conflict with each other. - Move future_event_relay_log_pos to rgi.
