bpo-40686: Fix compiler warnings on _zoneinfo.c (GH-23614)
"uint8_t day" is unsigned and so "day < 0" test is always true.
Remove the test to fix the following warnings on Windows:

modules\_zoneinfo.c(1224): warning C4068: unknown pragma
modules\_zoneinfo.c(1225): warning C4068: unknown pragma
modules\_zoneinfo.c(1227): warning C4068: unknown pragma

bpo-1635741: Refactor _threadmodule.c (GH-23793)
* Fix ExceptHookArgsType name: "_thread.ExceptHookArgs", instead of
  "_thread._ExceptHookArgs".
* PyInit__thread() no longer intializes interp->num_threads to 0:
  it is already done in PyInterpreterState_New().
* Use PyModule_AddType(), Py_NewRef() and Py_XNewRef().
* Replace str_dict variable with _Py_IDENTIFIER(__dict__).
* Remove assert(Py_IS_TYPE(obj, &Locktype)) from release_sentinel()
  to avoid having to retrive the type from this callback.
* Add thread_bootstate_free()
* Rename t_bootstrap() to thread_run()
* bootstate structure: rename keyw member to kwargs

bpo-42639: atexit._run_exitfuncs() uses sys.unraisablehook (GH-23779)
atexit._run_exitfuncs() now logs callback exceptions using
sys.unraisablehook, rather than logging them directly into
sys.stderr and raising the last exception.

Run GeneralTest of test_atexit in a subprocess since it calls
atexit._clear() which clears all atexit callbacks.

_PyAtExit_Fini() sets state->callbacks to NULL.

bpo-32381: pymain_run_file() uses PySys_FormatStderr() (GH-23778)
If config->run_filename doesn't exist, log the error into sys.stderr
using "%R" format, to escape properly unencodable characters (usually
with backslashreplace).

bpo-42639: Move atexit state to PyInterpreterState (GH-23763)
* Add _PyAtExit_Call() function and remove pyexitfunc and
  pyexitmodule members of PyInterpreterState. The function
  logs atexit callback errors using _PyErr_WriteUnraisableMsg().
* Add _PyAtExit_Init() and _PyAtExit_Fini() functions.
* Remove traverse, clear and free functions of the atexit module.

bpo-42639: atexit now logs callbacks exceptions (GH-23771)
At Python exit, if a callback registered with atexit.register()
fails, its exception is now logged. Previously, only some exceptions
were logged, and the last exception was always silently ignored.

Add _PyAtExit_Call() function and remove
PyInterpreterState.atexit_func member. call_py_exitfuncs() now calls
directly _PyAtExit_Call().

The atexit module must now always be built as a built-in module.

* Rename "atexitmodule_state" to "struct atexit_state".
* Rename "modstate" to "state".
* Rename "self" parameter to "module".
* test_atexit uses textwrap.dedent().
* Remove _Py_PyAtExit() function: inline it into atexit_exec().
* PyInterpreterState: rename pyexitfunc to atexit_func, rename
  pyexitmodule to atexit_module.

bpo-42536: GC track recycled tuples (GH-23623)
Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector:

- collections.OrderedDict.items
- dict.items
- enumerate
- functools.reduce
- itertools.combinations
- itertools.combinations_with_replacement
- itertools.permutations
- itertools.product
- itertools.zip_longest
- zip

Previously, they could have become untracked by a prior garbage collection.

bpo-40791: Make compare_digest more constant-time. (GH-20444)
* bpo-40791: Make compare_digest more constant-time.

The existing volatile `left`/`right` pointers guarantee that the reads will all occur, but does not guarantee that they will be _used_. So a compiler can still short-circuit the loop, saving e.g. the overhead of doing the xors and especially the overhead of the data dependency between `result` and the reads. That would change performance depending on where the first unequal byte occurs. This change removes that optimization.

(This is change #1 from https://bugs.python.org/issue40791 .)

* Add _PyImport_BootstrapImp() which fix a bootstrap issue: import

* Add create_builtin() sub-function, used by _imp_create_builtin().
* Initialize PyInterpreterState.import_func earlier, in
  pycore_init_builtins().
* Remove references to _PyImport_Cleanup(). This function has been
  renamed to finalize_modules() and moved to pylifecycle.c.

This change partically reverts
commit ad3252bad9
and the commit fe2978b3b9.

Many third party C extension modules rely on the ability of using
Py_TYPE() to set an object type: "Py_TYPE(obj) = type;" or to set an
object type using: "Py_SIZE(obj) = size;".

  by _PySignal_Fini().
* _PySignal_Fini() now closes sigint_event.
* IntHandler is no longer a global variable.
