This fixes TypedDict to work with get_type_hints and postponed evaluation of annotations across modules.
This is done by adding the module name to ForwardRef at the time the object is created and using that to resolve the globals during the evaluation.

The result of `int | int` is now `int`.
Fix comparison of the union type with non-hashable objects.
`int | str == {}` no longer raises a TypeError.

Patch by Erik Welch.
bpo-19072 (GH-8405) allows `classmethod` to wrap other descriptors, but this does
not work when the wrapped descriptor mimics classmethod. The current PR fixes
this.
In Python 3.8 and before, one could create a callable descriptor such that this
works as expected (see Lib/test/test_decorators.py for examples):
```python
class A:
@myclassmethod
def f1(cls):
return cls
@classmethod
@myclassmethod
def f2(cls):
return cls
```
In Python 3.8 and before, `A.f2()` return `A`. Currently in Python 3.9, it
returns `type(A)`. This PR make `A.f2()` return `A` again.
As of GH-8405, classmethod calls `obj.__get__(type)` if `obj` has `__get__`.
This allows one to chain `@classmethod` and `@property` together. When
using classmethod-like descriptors, it's the second argument to `__get__`--the
owner or the type--that is important, but this argument is currently missing.
Since it is None, the "owner" argument is assumed to be the type of the first
argument, which, in this case, is wrong (we want `A`, not `type(A)`).
This PR updates classmethod to call `obj.__get__(type, type)` if `obj` has
`__get__`.

* Fix issubclass() for None.
E.g. issubclass(type(None), int | None) returns now True.
* Fix issubclass() for virtual subclasses.
E.g. issubclass(dict, int | collections.abc.Mapping) returns now True.
* Fix crash in isinstance() if the check for one of items raises exception.

* zlib uses an UINT32_MAX sliding window for the output buffer
These funtions have an initial output buffer size parameter:
- zlib.decompress(data, /, wbits=MAX_WBITS, bufsize=DEF_BUF_SIZE)
- zlib.Decompress.flush([length])
If the initial size > UINT32_MAX, use an UINT32_MAX sliding window, instead of clamping to UINT32_MAX.
Speed up when (the initial size == the actual size).
This fixes a memory consumption and copying performance regression in earlier 3.10 beta releases if someone used an output buffer larger than 4GiB with zlib.decompress.

I tried to be relatively thorough and give lots of links.
One reason is that this wasn't deprecated very long; also it seems people running into this tend to not be familiar with similar APIs.
