BC
===

I've done my best to make this BC. It is now fully BC except from one case: If the logic in `ControllerResolver#getArguments()` is no longer used. If one would have used that method for custom argument resolving logic, it is no ignored. There should be a way that we can support both methods at the same time (in other words, create an argument resolver which uses the controller resolver).

A huge thanks to @Iltar for giving me the idea and helping me setting up this PR.
this should use ``$request->attributes->get()`` too
