MDEV-26473: mysqld got exception 0xc0000005 (rpl_slave_state/rpl_load_gtid_slave_state)
Problem:
========
During mysqld initialization, if the number of GTIDs added since
that last purge of the mysql.gtid_slave_pos tables is greater than
or equal to the –-gtid-cleanup-batch-size value, a race condition
can occur. Specifically, the binlog background thread will submit
the bg_gtid_delete_pending job to the mysql handle manager; however,
the mysql handle manager may not be initialized, leading to crashes.
Solution:
========
Force the mysql handle manager to initialize/start before the binlog
background thread is created.
