Serhiy Storchaka 09f3221fbb bpo-33652: Improve pickle support in the typing module. (GH-7123) 
Pickles of type variables and subscripted generics are now future-proof
and compatible with older Python versions.

bpo-32873: Treat type variables and special typing forms as immutable by copy and pickle (GH-6216) 
This also fixes python/typing#512
This also fixes python/typing#511

As was discussed in both issues, some typing forms deserve to be treated
as immutable by copy and pickle modules, so that:
* copy(X) is X
* deepcopy(X) is X
* loads(dumps(X)) is X  # pickled by reference

This PR adds such behaviour to:
* Type variables
* Special forms like Union, Any, ClassVar
* Unsubscripted generic aliases to containers like List, Mapping, Iterable

This not only resolves inconsistencies mentioned in the issues, but also
improves backwards compatibility with previous versions of Python
(including 3.6).

Note that this requires some dances with __module__ for type variables
(similar to NamedTuple) because the class TypeVar itself is define in typing,
while type variables should get module where they were defined.

bpo-32226: PEP 560: improve typing module (#4906) 
This PR re-designs the internal typing API using the new PEP 560 features.
However, there are only few minor changes in the public API.

Łukasz Langa f350a268a7 bpo-28556: typing.get_type_hints: better globalns for classes and modules (#3582) 
This makes the default behavior (without specifying `globalns` manually) more
predictable for users, finds the right globalns automatically.

Implementation for classes assumes has a `__module__` attribute and that module
is present in `sys.modules`.  It does this recursively for all bases in the
MRO.  For modules, the implementation just uses their `__dict__` directly.

This is backwards compatible, will just raise fewer exceptions in naive user
code.

Originally implemented and reviewed at https://github.com/python/typing/pull/470.
