Compatibility patches.
Please keep the following principles in mind:
* Keep imports local, so that importing this module does not cause too many
side effects by itself.
* Try to make patches idempotent, calling them multiple times should not do
harm. If that is not possible, ensure that the second call explodes.

Python 3 has deprecated formatargspec and requested that Signature
be used instead, however this requires a full reimplementation

Instead of introducing all the object-creation overhead and having
to reinvent from scratch, just copy their compatibility routine.
Utimately we would need to rewrite our "decorator" routine completely
which is not really worth it right now, until all Python 2.x support
is dropped.
