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.

…iases in Union (GH-24059)

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.

…l but processor) (#23010)

* 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.

…st` (#23758)

* 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.

… socket.ntohs and socket.htons (GH-23980)

There was a race condition in base64 in lazy initialization of multiple globals.

* Minor improvement to speed and space efficiency for the convolve() recipe
* Don't require convolve's kernel to be a sequence.

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.

…GH-23405)

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.
