48769a28ad bpo-35615: Fix crashes when copying a Weak{Key,Value}Dictionary. (GH-11384) (GH-11785) 
Protect dict iterations by wrapping them with _IterationGuard in the
following methods:

- WeakValueDictionary.copy()
- WeakValueDictionary.__deepcopy__()
- WeakKeyDictionary.copy()
- WeakKeyDictionary.__deepcopy__()
(cherry picked from commit 96d37dbcd2)

7a3dae056d Issue #15528: Add weakref.finalize to support finalization using 
weakref callbacks.

This is 2e446e87ac5b except that collections/__init__.py has been
modified to import proxy from _weakref instead of weakref.  This
eliminates an import cycle which seems to cause a problem on Unix but
not Windows.

bbe2f60b3c Issue #14159: Fix the len() of weak containers (WeakSet, WeakKeyDictionary, WeakValueDictionary) to return a better approximation when some objects are dead or dying. 
Moreover, the implementation is now O(1) rather than O(n).
Thanks to Yury Selivanov for reporting.

ecaab837b6 Committing the patch in issue 2965, so that weakref dicts have a closer 
interface to normal dictionaries.  keys(), values() and items() still return
iterators instead of views, but that can be fixed later (or not).
