Replace ReactComponentMixin with ReactReconciler

Instead of putting the shared code in a base class method, we use a wrapper
call around all invokations. That way they're free to add code before AND
after the non-shared code.

That way we ensure that component extensions don't need to implement
ReactComponentMixin and do super() calls into it. This helps to create a
tighter API for custom component extensions.

This provides the first step towards moving these methods to static
methods which allows to use a different dispatch mechanism instead of
virtual method calls. E.g. pattern matching.
