This is done to:

- update docstrings to current standards enforced by AC
- get proper naming for arguments of impl-functions (for example, self instead of obj and instance)
- strip boilerplate reducing current 16k lines of code to something little more manageable
- get a proper excuse to collapse overbloated PyTypeObject initializers by throwing out zeroes with designated initialization thanks to C99&11 being promoted. For example, EncodingMapType in unicodeobject.c reduced from 43 lines to 8, five times less.
