gh-91320: Use _PyCFunction_CAST() (#92251)
Replace "(PyCFunction)(void(*)(void))func" cast with
_PyCFunction_CAST(func).

Change generated by the command:

sed -i -e \
  's!(PyCFunction)(void(\*)(void)) *\([A-Za-z0-9_]\+\)!_PyCFunction_CAST(\1)!g' \
  $(find -name "*.c")

gh-89653: PEP 670: Functions don't cast pointers (#91697)
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.

bpo-45434: Only exclude <stdlib.h> in Python 3.11 limited C API (GH-29027)
The Python 3.11 limited C API no longer includes stdlib.h, stdio.h,
string.h and errno.h.

* Exclude Py_MEMCPY() from Python 3.11 limited C API.
* xxlimited C extension is now built with Python 3.11 limited C API.

bpo-41111: xxlimited.c defines Py_LIMITED_API (GH-25151)
xxlimited.c and xxlimited_35.c now define the Py_LIMITED_API macro,
rather than having to do it in the build recipe.

bpo-42111: Make the xxlimited module an example of best extension module practices (GH-23226)
- Copy existing xxlimited to xxlimited53 (named for the limited API version it uses)
- Build both modules, both in debug and release
- Test both modules

Pablo Galindo 1cf15af9a6 bpo-40217: Ensure Py_VISIT(Py_TYPE(self)) is always called for PyType_FromSpec types (reverts GH-19414) (GH-20264)
Heap types now always visit the type in tp_traverse. See added docs for details.

This reverts commit 0169d3003b.

bpo-32388: Remove cross-version binary compatibility requirement in tp_flags (GH-4944)
It is now allowed to add new fields at the end of the PyTypeObject struct without having to allocate a dedicated compatibility flag in tp_flags.

This will reduce the risk of running out of bits in the 32-bit tp_flags value.

Nick Coghlan 53f95024d7 Issue #24373: Eliminate PEP 489 test refleaks
_testmultiphase and xxlimited now use tp_traverse and
tp_finalize to avoid reference leaks encountered when
combining tp_dealloc with PyType_FromSpec (see
issue #16690 for details)

Nick Coghlan d5cacbb1d9 PEP 489: Multi-phase extension module initialization
Known limitations of the current implementation:

- documentation changes are incomplete
- there's a reference leak I haven't tracked down yet

The leak is most visible by running:

  ./python -m test -R3:3 test_importlib

However, you can also see it by running:

  ./python -X showrefcount

Importing the array or _testmultiphase modules, and
then deleting them from both sys.modules and the local
namespace shows significant increases in the total
number of active references each cycle. By contrast,
with _testcapi (which continues to use single-phase
initialisation) the global refcounts stabilise after
a couple of cycles.
