gh-121040: Use __attribute__((fallthrough)) (#121044)
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.

gh-113433: Automatically Clean Up Subinterpreters in Py_Finalize() (gh-121060)
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.

gh-117139: Convert the evaluation stack to stack refs (#118450)
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!

gh-120593: Fix const qualifier in _PyLong_CompactValue() (#121053)
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]

gh-120858: PyDict_Next should not lock the dict (#120859)
PyDict_Next no longer locks the dictionary in the free-threaded build. Locking
around individual PyDict_Next calls is not sufficient because the function
returns borrowed references and because it allows concurrent modifications
during the iteraiton loop.

The internal locking also interferes with correct external synchronization
because it may suspend outer critical sections created by the caller.
