For unsigned integer formats in the PyArg_Parse* functions,
accepting Python integers with value that is larger than
the maximal value the corresponding C type or less than
the minimal value for the corresponding signed integer type
is now deprecated.
* gh-135913: Document ob_refcnt, ob_type, ob_size
In `typeobj.rst`, instead of `:c:member:` it would be better to
use `.. c:member::` with a `:no-index:` option, see:
See ref. https://www.sphinx-doc.org/en/master/usage/domains/index.html#basic-markup
However, `c:member` currently does not support `:no-index:`.
* Turn the __future__ table to list-table.
This'll make it easier to add entries that need longer markup
* Semantic markup for __future__ feature descriptions.
* Document CO_* C macros.
Document behaviour of single-phase init. Call it "legacy".
Reorganize PyModule docs.
Move PyInit_modulename docs from the tutorial to reference documentation.
Move PyMODINIT_FUNC docs from generic macros to the new page.
Add doc stubs for `PYTHON_API_VERSION` & `PYTHON_ABI_VERSION`
Remove incorrect refcounts.dat entry for `PyModuleDef_Init`.
This removes the "Return value: Borrowed reference." note.
Instead, note that the function sometimes returns a borrowed reference,
sometimes as strong one.
(IMO, it's best to not think of `PyModuleDef` as a `PyObject` at all,
and act like it can't be reference-counted.)

Two special methods, __buffer__ and __release_buffer__ were added to
Python 3.12 by PEP 688. The C API Type Object documentation for slots
includes `tp_as_buffer`, and sub-slots `bf_getbuffer`, `bf_releasebuffer`
but does not refer to the Python Data Model version of those. Add the
missing references.
* Add "cyclic isolate" to the glossary.
* Add a new "Object Life Cycle" page.
* Improve docs for related API, with special focus on cross-references and warnings

After gh-130704, the interpreter replaces some uses of `LOAD_FAST` with
`LOAD_FAST_BORROW` which avoid incref/decrefs by "borrowing" references
on the interpreter stack when the bytecode compiler can determine that
it's safe.
This change broke some checks in C API extensions that relied on
`Py_REFCNT()` of `1` to determine if it's safe to modify an object
in-place. Objects may have a reference count of one, but still be
referenced further up the interpreter stack due to borrowing of
references.
This provides a replacement function for those checks.
`PyUnstable_Object_IsUniqueReferencedTemporary` is more conservative:
it checks that the object has a reference count of one and that it exists as a
unique strong reference in the interpreter's stack of temporary
variables in the top most frame.

* Skip sNaN's testing in 32-bit mode.
* Drop float_set_snan() helper.
* Use memcpy() workaround for sNaN's in PyFloat_Unpack4().
* Document, that sNaN's may not be preserved by PyFloat_Pack/Unpack API.
We replace it with _Py_GetMainModule(), and add _Py_CheckMainModule(), but both in the internal-only C-API. We also add _PyImport_GetModulesRef(), which is the equivalent of _PyImport_GetModules(), but which increfs before the lock is released.
This is used by a later change related to pickle and handling __main__.
