Marko Mäkelä 8a346f31b9 MDEV-17073 INSERT…ON DUPLICATE KEY UPDATE became more deadlock-prone
thd_rpl_stmt_based(): A new predicate to check if statement-based
replication is active. (This can also hold when replication is not
in use, but binlog is.)

que_thr_stop(), row_ins_duplicate_error_in_clust(),
row_ins_sec_index_entry_low(), row_ins(): On a duplicate key error,
only lock all index records when statement-based replication is in use.
