The unregister_security() and mod_unreg_security() functions were removed
because the upstream developers believe that it should not be possible to remove
security modules, "It is used only by out-of-tree modules, which are often
binary-only, illegal, abusive of the API and dangerous, e.g. silently
re-vectoring SELinux."
