commit 6abafdbb7cb79aec4dda159f177948e1ea77b7aa (HEAD -> bb-11.0-mdev-29676, upstream/bb-11.0-mdev-29676)

    MDEV-29676 Add query to set lock wait timeout when getting sts crd

    Set the lock wait timeout to 1 beforehand, and reset it afterwards, to

    avoid lock conflict caused by opening the same table twice in case of

    self-reference.

An mtr testcase is as follows. It needs to be improved as on a good commit, it does not clean up and fails the internal post-test check

This is caused by set_lock_wait_timeout() not checking for errors like conn->server_lost before executing query. Compare this to spider_db_query() which does the check through spider_db_before_query(). So we need to do something similar with setting the lock wait timeout.

Here's a PoC patch that fixes the issue and passes all existing tests. Will need to refine it:
