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]

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!

…e() (pythongh-121060)

This change makes things a little less painful for some users.  It also fixes a failing assert (pythongh-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.

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.

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.

…rs implementation in asyncio (python#121124)

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.

…rror=False (pythonGH-121056)

* 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.
