[PATCH v3 0/2] Predictable ELF destructor ordering (bug 30785)

[Florian Weimer <fweimer@redhat.com>]

Since my original submission, we have recieved a report that is likely
due to the non-working force_first handling in _dl_sort_maps when it is
called from dlclose.  So I want to propose this for integration once
more.  The ISV has received a test build with a backport, and hopefully
we'll know soon if this patch fixes there issue.

In v3, I have fixed an oversight in auditor integration spotted by
Adhemerval.  Somehow it had made it past my tests.  I'm also deferring
the _dl_sort_maps change to a future cleanup, so there are just two
patches left.

Thanks,
Florian
