Document the new semantics for setting and deleting a function's 

__dict__ attribute.  Deleting it, or setting it to a non-dictionary
result in a TypeError.  Note that getting it the first time magically
initializes it to an empty dict so that func.__dict__ will always
appear to be a dictionary (never None).

Closes SF bug #446645.

now use the Python warning framework (which makes it possible to
write filters for these warnings).
- A function's __dict__ (aka func_dict) will now always be a
dictionary. It used to be possible to delete it or set it to None,
but now both actions raise TypeErrors. It is still legal to set it
to a dictionary object. Getting func.__dict__ before any attributes
have been assigned now returns an empty dictionary instead of None.
