* We don't specify what happens on non-IEEE platforms.
* Use rather PY_LITTLE_ENDIAN to get native endianness.
* Mention that unpack functions don't fail in CPython.
* Mention that PyFloat_Pack8 doesn't fail in CPython.

* Drop DOUBLE_IS_ARM_MIXED_ENDIAN_IEEE754 macro.
* Use DOUBLE_IS_BIG/LITTLE_ENDIAN_IEEE754 to detect endianness of
float/doubles.
* Drop "unknown_format" code path in PyFloat_Pack/Unpack*().

Add a warning in the free-threading extensions howto explaining that
PyObject.ob_mutex is reserved for the critical section API and must not
be locked directly with PyMutex_Lock, as this can cause deadlocks.
Extension authors who need their own lock should add a separate PyMutex
field to their object struct.
Also add an ob_mutex member entry under PyObject in the C API reference
(Doc/c-api/structures.rst) with a cross-reference to the howto.

Python.h now also includes <string.h> in the limited C API version 3.11
and newer to fix the Py_CLEAR() macro which uses memcpy().
Add a Py_CLEAR() test in test_cext.
Modify also _Py_TYPEOF to use C23 typeof() if available.
When integrating slots-based module creation is with the inittab,
which currently requires PyModuleDef, it would be convenient to
reuse the the same slots array for the MethodDef.
Allow slots that match what's already present in the PyModuleDef.
- Group the macros
- Roughly order them to put the most important ones first
- Add expansions where it makes sense; especially if there's
an equivalent in modern C or a common compiler

These had a docs-only deprecation notice since the first version of the docs in this repo. Nowadays we call things “soft deprecated” if there's just a note in the docs.
The deprecated directive needs a version, I went with the first one that had the notice (2.0; it's not in 1.6):
- https://docs.python.org/release/2.0/api/memoryInterface.html
- https://docs.python.org/release/1.6/api/memoryInterface.html
Since PEP 445, they are now direct aliases; there are no (additional) binary compatibility concerns over the preferred names.
