[issue15029] Update Defining New Types chapter according to PEP 253

[Mateusz Loskot]

New submission from Mateusz Loskot <mateusz at loskot.net>:

The chapter '2. Defining New Types" in the Python 3.2 documentation [1] does not cover all important elements, especially in the subsection 2.1.4. Subclassing other types.

The accepted PEP 253 [2] provides much more detailed and thorough explanation for Python C API users willing to define and subclass new types, than the official manual.

I'd like to suggest update of the manual with information enclosed in the PEP 253. In fact, the PEP's sections like

* Preparing a type for subtyping
* Creating a subtype of a built-in type in C

could be copied with little editing, IMHO.

The PEP 253 really seems to be a must-read document for Python C API users.
