1. Use pkg-config to check for ncursesw/panelw. If that fails, use
pkg-config to check for ncurses/panel.
2. Regardless of pkg-config output, search for curses/panel headers, so
we're sure we have all defines in pyconfig.h.
3. Regardless of pkg-config output, check if libncurses or libncursesw
contains the 'initscr' symbol; if it does _and_ pkg-config failed
earlier, add the resulting -llib linker option to CURSES_LIBS.
Ditto for 'update_panels' and PANEL_LIBS.
4. Wrap the rest of the checks with WITH_SAVE_ENV and make sure we're
using updated LIBS and CPPFLAGS for those.
Add the PY_CHECK_CURSES convenience macro.
asyncio earlier relied on subprocess module to send signals to the process, this has some drawbacks one being that subprocess module unnecessarily calls waitpid on child processes and hence it races with asyncio implementation which internally uses child watchers. To mitigate this, now asyncio sends signals directly to the process without going through the subprocess on non windows systems. On Windows it fallbacks to subprocess module handling but on windows there are no child watchers so this issue doesn't exists altogether.
Add dedicated subsection for `home()`, `expanduser()`, `cwd()`,
`absolute()`, `resolve()` and `readlink()`. The position of this section
keeps all the `Path` constructors (`Path()`, `Path.from_uri()`,
`Path.home()` and `Path.cwd()`) near the top. Within the section, closely
related methods are kept adjacent. Specifically:
-.`home()` and `expanduser()` (the former calls the latter)
- `cwd()` and `absolute()` (the former calls the latter)
- `absolute()` and `resolve()` (both make paths absolute)
- `resolve()` and `readlink()` (both read symlink targets)
- Ditto `cwd()` and `absolute()`
- Ditto `absolute()` and `resolve()`
The "Other methods" section is removed.
In some cases, previously computed as (nan+nanj), we could
recover meaningful component values in the result, see
e.g. the C11, Annex G.5.2, routine _Cdivd().
* parse_intermixed_args() now raises ArgumentError instead of calling
error() if exit_on_error is false.
* Internal code now always raises ArgumentError instead of calling
error(). It is then caught at the higher level and error() is called if
exit_on_error is true.
On Windows, test_cext and test_cppext now pass /WX flag to the MSC
compiler to treat all compiler warnings as errors. In verbose mode,
these tests now log the compiler commands to help debugging.
Change Py_BUILD_ASSERT_EXPR implementation on Windows to avoid a
compiler warning about an unnamed structure.
The check for whether the log file is a real file is expensive on NFS
filesystems. This commit reorders the rollover condition checking to
not do the file type check if the expected file size is less than the
rotation threshold.

Indentation of code blocks made them nested
"Version changed" is better placed after the code block
* Fix formatting for tests
* fix code indentation for autotests
* Fix identation for autotests
* Remove duplication of the parameters' description
* Rearrange parameters description in a correct order

Fix warnings when using -Wimplicit-fallthrough compiler flag.
Annotate explicitly "fall through" switch cases with a new
_Py_FALLTHROUGH macro which uses __attribute__((fallthrough)) if
available. Replace "fall through" comments with _Py_FALLTHROUGH.
Add _Py__has_attribute() macro. No longer define __has_attribute()
macro if it's not defined. Move also _Py__has_builtin() at the top
of pyport.h.

This change makes things a little less painful for some users. It also fixes a failing assert (gh-120765), by making sure all subinterpreters are destroyed before the main interpreter. As part of that, we make sure Py_Finalize() always runs with the main interpreter active.
This PR sets up tagged pointers for CPython.
The general idea is to create a separate struct _PyStackRef for everything on the evaluation stack to store the bits. This forces the C compiler to warn us if we try to cast things or pull things out of the struct directly.
Only for free threading: We tag the low bit if something is deferred - that means we skip incref and decref operations on it. This behavior may change in the future if Mark's plans to defer all objects in the interpreter loop pans out.
This implies a strict stack reference discipline is required. ALL incref and decref operations on stackrefs must use the stackref variants. It is unsafe to untag something then do normal incref/decref ops on it.
The new incref and decref variants are called dup and close. They mimic a "handle" API operating on these stackrefs.
Please read Include/internal/pycore_stackref.h for more information!

Remove the const qualifier of the argument of functions:
* _PyLong_IsCompact()
* _PyLong_CompactValue()
Py_TYPE() argument is not const.
Fix the compiler warning:
Include/cpython/longintrepr.h: In function ‘_PyLong_CompactValue’:
Include/pyport.h:19:31: error: cast discards ‘const’ qualifier from
pointer target type [-Werror=cast-qual]
(...)
Include/cpython/longintrepr.h:133:30: note: in expansion of macro
‘Py_TYPE’
assert(PyType_HasFeature(Py_TYPE(op), Py_TPFLAGS_LONG_SUBCLASS));
