SF bug #1193966: Weakref types documentation misplaced

The information about supporting weakrefs with types defined in C extensions
is moved to the Extending & Embedding manual. Py_TPFLAGS_HAVE_WEAKREFS is
no longer mentioned since it is part of Py_TPFLAGS_DEFAULT.

Make weak references subclassable:

Fri, 02 Jul 2004 18:57:45 +0000

Make weak references subclassable:

- weakref.ref and weakref.ReferenceType will become aliases for each
other

- weakref.ref will be a modern, new-style class with proper __new__
and __init__ methods

- weakref.WeakValueDictionary will have a lighter memory footprint,
using a new weakref.ref subclass to associate the key with the
value, allowing us to have only a single object of overhead for each
dictionary entry (currently, there are 3 objects of overhead per
entry: a weakref to the value, a weakref to the dictionary, and a
function object used as a weakref callback; the weakref to the
dictionary could be avoided without this change)

- a new macro, PyWeakref_CheckRefExact(), will be added

- PyWeakref_CheckRef() will check for subclasses of weakref.ref

This closes SF patch #983019.

Patch supplied by Burton Radons for his own SF bug #487390: Modifying
type.__module__ behavior.

This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this). Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right. Apologies if they're
not. This also touches the weakref docs, which contains a sample type
object initializer. It also touches the mmap test output, because the
mmap type's repr is included in that output. It touches object.h to
put the correct description in a comment.
