Subject: [PATCH 1/2] BZ 2124214 - schema compat plugin deadlock on delete post
op
Bug description:
backends locks (SC map and retroCL) are acquired in
the opposite order
(https://bugzilla.redhat.com/show_bug.cgi?id=2124214#c17)
Fix description:
Credits of the fix are to Pierre Rogier who found
a reproducible testcase, did the fix and verified it.
In specific condition of retroCL trimming the DEL
callback of the SC should check if the backend should
be ignored

Subject: [PATCH 1/2] Test the case when container is a child of the target DN
We can have target DN both inside or outside of a container.
Previously, the code did not look into the latter one. When container is
a child of the target DN (like using IPA's base DN instead of
cn=compat,$BASE_DN) and a search was done with a subtree scope, the
check failed.
With this change a subtree scope search which starts with a base DN
that includes a compat tree's container would be considered for the
search.

Subject: [PATCH 2/2] Identify the container without search base check
Ignore the actual search base when identifying whether a target DN is
within a known data container. The reason is that we need to know
whether a search would have to descent into a particular container. The
scope validation will happen later.
