bpo-39264: Fix UserDict.get() to account for __missing__() (GH-17910)
Here's the patch according to the discussion at the [Python-Dev mailing list](https://mail.python.org/archives/list/python-dev@python.org/thread/SDXOEMAEM6KQ3CQCJVBVRT5QNSPAVU6X/).
UserDict.get() will match dict's behavior and not call `__missing__`.

bpo-26579: Add object.__getstate__(). (GH-2821)
Copying and pickling instances of subclasses of builtin types
bytearray, set, frozenset, collections.OrderedDict, collections.deque,
weakref.WeakSet, and datetime.tzinfo now copies and pickles instance attributes
implemented as slots.

bpo-27275: Change popitem() and pop() methods of collections.OrderedDict (GH-27530)
* Unify the C and Python implementations of OrderedDict.popitem().

The C implementation no longer calls ``__getitem__`` and ``__delitem__``
methods of the OrderedDict subclasses.

* Change popitem() and pop() methods of collections.OrderedDict

For consistency with dict both implementations (pure Python and C)
of these methods in OrderedDict no longer call __getitem__ and
__delitem__ methods of the OrderedDict subclasses.

Previously only the Python implementation of popitem() did not
call them.
