* Renamed assertLeadingPadding function to match logic
* Added a separate error message for discontinuous padding
* Updated the tests for discontinuous padding
- Refactor module/script handling to share an interface (check method).

binascii.a2b_base64 gains a strict_mode= parameter. When enabled it will raise an
error on input that deviates from the base64 spec in any way. The default remains
False for backward compatibility.

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.

It no longer depends on the order of arguments.

GH-23638 introduced a new test for Accept: headers in CGI HTTP servers. This test serializes all of os.environ on the server side. For non-UTF8 locales this can fail for some Unicode characters found in environment variables. This change fixes the HTTP_ACCEPT test.
Patch by Erik Welch.
bpo-19072 (#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 #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.
Fix incorrect handling of exceptions when interpreting dialect objects in
the csv module. Not clearing exceptions between calls to
PyObject_GetAttrString() causes assertion failures in pydebug mode (or with
assertions enabled).
Add a minimal test that would've caught this (passing None as dialect, or
any object that isn't a csv.Dialect subclass, which the csv module allows
and caters to, even though it is not documented.) In pydebug mode, the test
triggers the assertion failure in the old code.
