Add `_SimpleCData._type_` docs.
Add type codes to the summary table.
Cross-link `struct`, `array`, and `ctypes`; throw in `numpy` too.
(Anyone wanting to add a code should be aware of those.)
Add `py_object`, and `VARIANT_BOOL` for completeness.
Add base32 encoder and decoder functions implemented in
C to the binascii module and use them to greatly improve the
performance and reduce the memory usage of the existing
base32 codec functions in the base64 module.
* Put the "Loading shared libraries" section first
* Adjust formatting at the end of the section
* In "Finding shared libraries", add more text about what's going on
* Move the stub function doc for find_library into "Finding shared libraries"
* Also move the sister function, find_msvcrt. That's on the chopping block,
but not removed now.
* Add the alphabet parameter in functions b2a_base64(), a2b_base64(),
b2a_base85(), and a2b_base85().
* And a number of "*_ALPHABET" constants.
* Remove b2a_z85() and a2b_z85().
* 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.

- Add leading space so that the spacing between the previous annotation
and the thread safety annotation looks correct.
- Remove trailing period from the link to the thread safety level.

* Struct.__new__() will require a mandatory argument (format)
* Calls of __init__() method with a different format argument on initialized
Struct are deprecated

* 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.
