* gh-53502: Fixes for tests in gh-113363
* Use 32-bit compatible date in test_dump_naive_datetime_with_aware_datetime_option
* Saving non-aware datetimes will use the old behaviour regardless of the aware_datimetime setting
* gh-113536: Expose `os.waitid` on macOS
This API has been available on macOS for a long time, but was
explicitly excluded due to unspecified problems with the API
in ancient versions of macOS.
* Document that the API is available on macOS starting in Python 3.13
The length field of StgDictObject for Structure class contains now
the total number of items in ffi_type_pointer.elements (excluding
the trailing null).
The old behavior of using the number of elements in the parent class can
cause the array to be truncated when it is copied, especially when there
are multiple layers of subclassing.

Run expensive tests for walking and globbing from `test_pathlib` but not
`test_pathlib_abc`. The ABCs are not as tightly optimised as the classes
in top-level `pathlib`, and so these tests are taking rather a long time on
some buildbots. Coverage of the main `pathlib` classes should suffice.
Rework error handling in the C preprocessor helper. Instead of monkey-
patching the cpp.Monitor.fail() method from within clinic.py, rewrite
cpp.py to use a subclass of the ClinicError exception. As a side-effect,
ClinicError is moved into Tools/clinic/libclinic/errors.py.
Yak-shaving in preparation for putting cpp.py into libclinic.
The `pathlib._abc` module will be made available as a PyPI backport
supporting Python 3.8+. The `warnings._deprecated()` function was only
added last year, and it's private from an external package perspective, so
here we switch to `warnings.warn()` instead.
Do not use the locale-specific default encoding in `PathBase.read_text()`
and `write_text()`. Locale settings shouldn't influence the operation of
these base classes, which are intended mostly for implementing rich paths
on *nonlocal* filesystems.
Previously some error messages complained about incompatible
combinations of directives that are not contained in the format string.

* gh-112532: Use separate mimalloc heaps for GC objects
In `--disable-gil` builds, we now use four separate heaps in
anticipation of using mimalloc to find GC objects when the GIL is
disabled. To support this, we also make a few changes to mimalloc:
* `mi_heap_t` and `mi_tld_t` initialization is split from allocation.
This allows us to have a `mi_tld_t` per-`PyThreadState`, which is
important to keep interpreter isolation, since the same OS thread may
run in multiple interpreters (using different PyThreadStates.)
* Heap abandoning (mi_heap_collect_ex) can now be called from a
different thread than the one that created the heap. This is necessary
because we may clear and delete the containing PyThreadStates from a
different thread during finalization and after fork().
* Use enum instead of defines and guard mimalloc includes.
* The enum typedef will be convenient for future PRs that use the type.
* Guarding the mimalloc includes allows us to unconditionally include
pycore_mimalloc.h from other header files that rely on things like
`struct _mimalloc_thread_state`.
* Only define _mimalloc_thread_state in Py_GIL_DISABLED builds
