bpo-42536: GC track recycled tuples (GH-23623)

2020-12-05T03:45:57+00:00

Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector:

- collections.OrderedDict.items
- dict.items
- enumerate
- functools.reduce
- itertools.combinations
- itertools.combinations_with_replacement
- itertools.permutations
- itertools.product
- itertools.zip_longest
- zip

Previously, they could have become untracked by a prior garbage collection.

Py_BUILD_CORE_MODULE macro defined.

When structmember.h is used, add a comment explaining that
PyMemberDef is used.
