0fa4dd0747 MDEV-29433 innodb.lock_delete_updated is unstable
Use suspend thread syncpoint instead of include/wait_condition.inc to
make sure DELETE created waiting lock before the next UPDATE begins
locking.

86c1bf118a MDEV-27992 DELETE fails to delete record after blocking is released
MDEV-27025 allows to insert records before the record on which DELETE is
locked, as a result the DELETE misses those records, what causes serious ACID
violation.

Revert MDEV-27025, MDEV-27550. The test which shows the scenario of ACID
violation is added.
