…ule practices (GH-23226)

- Copy existing xxlimited to xxlimited53 (named for the limited API version it uses)
- Build both modules, both in debug and release
- Test both modules

Removed PyModule_GetWarningsModule() which is useless due to 
the _warnings module was converted to a builtin module in 2.6.

Fix encoding name when running a ".pyc" file on Windows:
PyRun_SimpleFileExFlags() now uses the correct encoding to decode the
filename.

* Add pyrun_file() subfunction.
* Add pyrun_simple_file() subfunction.
* PyRun_SimpleFileExFlags() now calls _Py_fopen_obj() rather than
  _Py_fopen().

…GH-23662)

The solution in gh##13236 is too strict because it
effectively requires the use of Sphinx >= 2.0. It is not too difficult to
make the same solution more robust so it works with all normal versions
of Sphinx.

… match distutils (GH-22088)

Remove obsolete workaround that prevented running files with
shortcuts when using new universal2 installers built on macOS 11.
Ignore buggy 2nd run_module_event call.

… set (GH-23653)

It was used to implement now removed asyncio.Task.all_tasks().

… call its __bool__ function (GH23613)

Check if NonCallableMock's spec_arg is not None instead of call its __bool__ function

…icAlias (GH-23656)

Use `_PyArg_NoKeywords` instead of `_PyArg_NoKwnames` when checking the `kwds` tuple when creating `GenericAlias`. This fixes an interpreter crash when passing in keyword arguments to `GenericAlias`'s constructor.

Needs backport to 3.9.

#23638)

Do the same for PyTuple_SET_ITEM().

If no explicit macOS SDK was specified, setup.py should check for
Tcl and TK frameworks in /Library/Frameworks; the previous commit
inadvertently broke that test.

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.

Raise an ImportWarning when the import system falls back on load_module(). As for implementations of load_module(), raise a DeprecationWarning.

…t of range (GH-23633)

This can happen when a file was edited after it was imported.

Fix test_doctest.py failures for VxWorks by avoiding exact error message checks. (better for everyone all around)

https://bugzilla.redhat.com/show_bug.cgi?id=1866884 is fixed in gdb
10.1 (failed to reproduce on gdb-10.1-1.fc34.aarch64).

…have a line number (GH-23636)

Don't forget the entry block when ensuring that all exits have a line number.

…ne numbers (GH-23632)

Fix issue when dis failed to parse function that has only annotations

Write also unit tests on Py_NewRef() and Py_XNewRef().
