Also updated `make -C htmlview` so it used a full path with `file://`, because the original didn't open the page (macOS).
For example:
```sh
cd Doc
# Doesn't open anything:
python3 -c "import webbrowser; webbrowser.open('build/html/index.html')"
# Opens the docs page e.g. file:///Users/hugo/github/cpython/Doc/build/html/index.html :
python3 -c "import os, webbrowser; webbrowser.open('file://' + os.path.realpath('build/html/index.html'))"
```

# Adding 'required' to names in Lib.argparse.Action
gh-91832:
Added 'required' to the list `names` in `Lib.argparse.Action`.
Changed constant strings that test the Action object.

`HOSTRUNNER` is a program which can be used to run `BUILDPYTHON` for the host platform (for example, `python.js` requires `node`).
Also change depedencies from `build_all` to `all` so that targets which can't build everything (e.g. WASM) can still run `buildbottest` and `pythoninfo`.

When Python is built with "./configure --enable-pystats" (if the
Py_STATS macro is defined), the _Py_GetSpecializationStats() function
must be exported, since it's used by the _opcode extension which is
built as a shared library.
Reduce the complexity from O((M+N)^2) to O(M*N), where M and N are the length
of __args__ for both operands (1 for operand which is not a UnionType).
As a consequence, the complexity of parameter substitution in UnionType has
been reduced from O(N^3) to O(N^2).

The warning emitted by the Python parser for a numeric literal
immediately followed by keyword has been changed from deprecation
warning to syntax warning.
Fix C++ compiler warnings about "old-style cast"
(g++ -Wold-style-cast) in the Python C API. Use C++
reinterpret_cast<> and static_cast<> casts when the Python C API is
used in C++.
Example of fixed warning:
Include/object.h:107:43: error: use of old-style cast to
‘PyObject*’ {aka ‘struct _object*’} [-Werror=old-style-cast]
#define _PyObject_CAST(op) ((PyObject*)(op))
Add _Py_reinterpret_cast() and _Py_static_cast() macros.
It was initially added to support atomic groups, but that
support was never fully implemented, and CALL was only left
in the compiler, but not interpreter and parser.
ATOMIC_GROUP is now used to support atomic groups.
If use a non-builtin codec, partially implemented in Python
(e.g. ISO-8859-15), a new RecursionError (with empty error message)
can be raised while handle a RecursionError.
Testing for error message was needed to distinguish
a recursion error from arbitrary RuntimeError. After introducing
RecursionError, it became unnecessary.
Copied from typing-extensions (python/typing#1054, python/typing#1120).
Documentation is intentionally omitted, so we can focus on getting the
runtime part in before the feature freeze.
Just in case there is ever an issue with _posixsubprocess's use of
vfork() due to the complexity of using it properly and potential
directions that Linux platforms where it defaults to on could take, this
adds a failsafe so that users can disable its use entirely by setting
a global flag.
No known reason to disable it exists. But it'd be a shame to encounter
one and not be able to use CPython without patching and rebuilding it.
See the linked issue for some discussion on reasoning.
Also documents the existing way to disable posix_spawn.
Move the following API from Include/opcode.h (public C API) to a new
Include/internal/pycore_opcode.h header file (internal C API):
* EXTRA_CASES
* _PyOpcode_Caches
* _PyOpcode_Deopt
* _PyOpcode_Jump
* _PyOpcode_OpName
* _PyOpcode_RelativeJump
Fix signal.NSIG value on FreeBSD to accept signal numbers greater
than 32, like signal.SIGRTMIN and signal.SIGRTMAX.
* Add Py_NSIG constant.
* Add pycore_signal.h internal header file.
* _Py_Sigset_Converter() now includes the range of valid signals in
the error message.
In the limited C API version 3.11 and newer, the following functions
no longer cast their object pointer argument with _PyObject_CAST() or
_PyObject_CAST_CONST():
* Py_REFCNT(), Py_TYPE(), Py_SIZE()
* Py_SET_REFCNT(), Py_SET_TYPE(), Py_SET_SIZE()
* Py_IS_TYPE()
* Py_INCREF(), Py_DECREF()
* Py_XINCREF(), Py_XDECREF()
* Py_NewRef(), Py_XNewRef()
* PyObject_TypeCheck()
* PyType_Check()
* PyType_CheckExact()
Split Py_DECREF() implementation in 3 versions to make the code more
readable.
Update the xxlimited.c extension, which uses the limited C API
version 3.11, to pass PyObject* to these functions.
* Add a new :gh:`...` role for GitHub issues.
* Fix a GitHub id to use the :gh: role.
* Add Misc/NEWS entry.
* Refactoring and rephrasing.

Similar to the rewrite of email/mime/image.py and associated test after the
deprecation of imghdr.py, thisrewrites email/mime/audio.py and associated
tests after the deprecation of sndhdr.py.
Closes #91885
The test relies on precision being set to 9, but some ways of
invoking this test leave it set to 28 instead. I don't know
exactly how it happens, but setting the precision directly should
make the behavior consistent.
