Use a `_PyStackRef` and defer the reference to `f_funcobj` when
possible. This avoids some reference count contention in the common case
of executing the same code object from multiple threads concurrently in
the free-threaded build.
* Detect source file encoding.
* Use the "replace" error handler even for UTF-8 (default) encoding.
* Remove the BOM.
* Fix detection of too long lines if they contain NUL.
* Return the head rather than the tail for truncated long lines.
This allows to use positional argument with nargs='*' and without default
in mutually exclusive group and improves error message about required
arguments.
Arguments with the value identical to the default value (e.g. booleans,
small integers, empty or 1-character strings) are no longer considered
"not present".
- If setting `_fields_` fails, e.g. with AttributeError, don't set the attribute in `__dict__`
- Document the “finalization” behaviour
- Beef up tests: add `getattr`, test Union as well as Structure
- Put common functionality in a common function

The code changes for warning related to `__package__` landed in Python 3.12. `__cached__` doesn't have any changes as it isn't used but only set by the import system.
In case of usage a long command along with max_help_position more than
the length of the command, the command's help was incorrectly started
on the new line.

We were sometimes passing None as the globals argument to eval(), which makes it
inherit the globals from the calling scope. Instead, ensure that globals is always
non-None. The test was passing accidentally because I passed "annotationlib" as a
module object; fix that. Also document the parameters to ForwardRef() and remove
two unused private ones.

The term `Immutable` in the `sequence` entry of the glossary is used incorrectly, in fact dicts accepts hashable keys, which is not the same as immutable.
Lower the C recursion limit for HPPA, PPC64 and SPARC, as they use
relatively large stack frames that cause e.g. `test_descr` to hit
a stack overflow. According to quick testing, it seems that values
around 8000 are max for HPPA and PPC64 (ELFv1 ABI) and 7000 for SPARC64.
To keep things safe, let's use 5000 for PPC64 and 4000 for SPARC.

https://github.com/python/cpython/issues/88496 replaced text.update with text.update_idletasks in colorizer.py and outwin.py to fix test failures on macOS. While theoretically correct, the result was Shell freezing when receiving continuous short strings to print. Test: `while 1: 1`.
The guess is that there is no idle time in which to do the screen update. Reverting the change in one of the files,
outwin, fixes the issue. Colorizer runs ever 1/20 second and seems to work fine.
When running test-outwin on macOS, alias 'update'
to 'update_idletasks on the text used for testing.
