libvirt currently exhibits undefined behavior due to pthread mutex

Add a warning if such a case is detected, so we can start on fixing the
issues.
I expect this to be even harder to fix than to detect. BTW: in the past
I used to play with:
https://github.com/dbadapt/mutrace
which looked like it could detect some locking problems. I think I even
had some patches locally for easier debugging of libvirt. But I can't
find that repo anymore.
Oh, and then there's DRD tool in valgrind, but I can't find the right
combination of arguments to make it produce anything usable.
