…bits` (pythonGH-118292) (python#118796)

Use relaxed atomics when reading / writing to the field. There are still a
few places in the GC where we do not use atomics. Those should be safe as
the world is stopped.

…ded build (pythonGH-118723) (python#118863)

The `list_preallocate_exact` function did not zero initialize array
contents. In the free-threaded build, this could expose uninitialized
memory to concurrent readers between the call to
`list_preallocate_exact` and the filling of the array contents with
items.

… current file (pythonGH-118808) (python#118866)

Some embedders and extensions include parts of the internal API. The
pycore_mimalloc.h file is transitively include by a number of other
internal headers. This avoids include errors for code that was
already including those headers.

…H-118862) (python#118867)

Avoid immortalizing objects in tests that verify garbage collection of
classes or modules.

This fixes test_ordered_dict and test_struct.

…ules (pythonGH-118722) (python#118870)

Using `race:` filters out warnings if the function appears anywhere in
the stack trace. This can hide a lot of unrelated warnings, especially
for a function like `_PyEval_EvalFrameDefault`, which is somewhere on
the stack more often than not.

Change all free-threaded suppressions to `race_top:`, which only matches
the top frame, and add any new suppressions this exposes.

…H-118797) (pythonGH-118903)

pythongh-118789: Restore hidden `_PyWeakref_ClearRef` (pythonGH-118797)

_PyWeakref_ClearRef was previously exposed in the public C-API, although
it begins with an underscore and is not documented. It's used by a few
C-API extensions. There is currently no alternative public API that can
replace its use.

_PyWeakref_ClearWeakRefsExceptCallbacks is the only thread-safe way to
use _PyWeakref_ClearRef in the free-threaded build. This exposes the C
symbol, but does not make the API public.

…andbelow` in `secrets.rst` (pythonGH-118098) (pythonGH-118906)

Correct the argument names for `secrets.choice` and `secrets.randbelow` in `secrets.rst` (pythonGH-118098)

Correct the argument names for `secrets.choice` and `secrets.randbelow` in `secrets.rst`.

…thon#118905)

`_Py_qsbr_unregister` is called when the PyThreadState is already
detached, so the access to `tstate->qsbr` isn't safe without locking the
shared mutex. Grab the `struct _qsbr_shared` from the interpreter
instead.
(cherry picked from commit 33d2019)
