Re-implement Python -fastproxy option.

Browse source 
The previous implementation failed with Python 3 and abstract base clases.
The new implementation replaces the Python 2 implementation using new.instancemethod with C API PyMethod_New to match the equivalent Python 3 implementation which uses PyInstanceMethod_New.

Closes #1310
