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.
