A compiler that doesn't define `__has_builtin` will error out when it is
used on the same line as the check for it.

In is_typing_name(), va_end() is not always called before the
function returns. It is undefined behavior to call va_start()
without also calling va_end().
If __stdout__ is not attached to terminal, try to use __stderr__
if it is attached to terminal, or open the terminal device, or
use regular file as terminal, but some functions will be untested
in the latter case.
Previously this didn't raise an error. Now it will:
```python
from collections.abc import Callable
isinstance(int, list | Callable[..., str])
```
Also added tests in Union since there were previously none for stuff like ``isinstance(list, list | list[int])`` either.
Backport to 3.9 not required.

* Add test capturing missed expectation with uname_result._replace.
* bpo-42163: Override uname_result._make to allow uname_result._replace to work (for everything but 'processor'.
* Replace hard-coded length with one derived from the definition.
* Add test capturing missed expectation with copy/deepcopy on namedtuple (bpo-42189).
* bpo-42189: Exclude processor parameter when constructing uname_result.
* In _make, rely on __new__ to strip processor.
* Add blurb.
* iter is not necessary here.
* Rely on num_fields in __new__
* Add test for slices on uname
* Add test for copy and pickle.

* import pickle
* Fix equality test after pickling.
* Simply rely on __reduce__ for pickling.

* bpo-42382: In importlib.metadata, `EntryPoint` objects now expose a `.dist` object referencing the `Distribution` when constructed from a `Distribution`.
Also, sync importlib_metadata 3.3:
- Add support for package discovery under package normalization rules.
- The object returned by `metadata()` now has a formally-defined protocol called `PackageMetadata` with declared support for the `.get_all()` method.
* Add blurb
* Remove latent footnote.
There was a typo, we were checking if the "GITHUB_BASE_REF" string
literal was empty instead of the $GITHUB_BASE_REF value. When
$GITHUB_BASE_REF is empty, the action that triggered the run was not a
pull request, so we always run the full test suite.

Added --disable-test-modules option to the configure script:
don't build nor install test modules.

The descriptions of the `codes` and `messages` dictionaries in
`xml.parsers.expat.errors` were swapped, and this commit swaps them
back. For example, `codes` maps string descriptions of errors to numeric
error codes, not the other way around.
