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-42615: Delete redundant jump instructions that only bypass empty blocks (GH-23733)
* Delete jump instructions that bypass empty blocks

* Add news entry

* Explicitly check for unconditional jump opcodes

Using the is_jump function results in the inclusion of instructions like
returns for which this optimization is not really valid. So, instead
explicitly check that the instruction is an unconditional jump.

* Handle conditional jumps, delete jumps gracefully

* Ensure b_nofallthrough and b_reachable are valid

* Add test for redundant jumps

* Regenerate importlib.h and edit Misc/ACKS

* Fix bad whitespace

* 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-42644: Validate values in logging.disable() (#23786)
* bpo-42644: Validate values in logging.disable()

Technically make the value of manager a property that checks and convert
values assigned to it properly. This has the side effect of making
`logging.disable` also accept strings representing the various level of
warnings.

We want to validate the type of the disable attribute at assignment
time, as it is later compared to other levels when emitting warnings and
would generate a `TypeError: '>=' not supported between ....` in a
different part of the code base, which can make it difficult to track
down.

When assigned an incorrect value; it will raise a TypeError when the
wrong type, or ValueError if an invalid str.

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-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.

bpo-41877: Check for misspelled speccing arguments (GH-23737)
patch, patch.object and create_autospec silently ignore misspelled
arguments such as autospect, auto_spec and set_spec. This can lead
to tests failing to check what they are supposed to check.

This change adds a check causing a RuntimeError if the above
functions get any of the above misspellings as arguments. It also
adds a new argument, "unsafe", which can be set to True to disable
this check.

Also add "!r" to format specifiers in added error messages.

code today.  We need it to support parsing modern 3.8 and 3.9 constructs.

Also add tests for complex *expr and **expr's.
