MDEV-4506: Parallel replication
MDEV-5217: Incorrect event pos update leading to corruption of reading of events from relay log
The rli->event_relay_log_pos was sometimes undated incorrectly when using
parallel replication, especially around relay log rotates. This could cause
the SQL thread to seek into an invalid position in the relay log, resulting in
errors about invalid events or even random corruption in some cases.
