…ectly after raising or reraising an exception (GH-23803)

* Ensure that f_lasti is set correctly after an exception is raised to conform to PEP 626.

* Update importlib

* Add NEWS.

The issue being resolved is shown in the 3.10 docs (if you select docs for older versions you won't see a visual glitch).

The newer sphinx version that produces the 3.10 docs doesn't treat the backslash to escape things in some situations it previously did.

The quoted sentence can be found from the last paragraph of RFC 2046, Section 5.1, while the content of RFC 2026 is unrelated to this module.

The existing method is indented one too many times which
makes it look like a sub-method of print_callees().

Regression in 8d59eb1.

This is a trivial refactor in preparation for a fix for bpo-38323.

"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

Add the following symbols to python3dll.c:

* PyFrame_GetCode (bpo-40421)
* PyFrame_GetLineNumber (bpo-40421)
* PyModule_AddObjectRef (bpo-1635741)
* PyObject_CallNoArgs (bpo-37194)
* PyThreadState_GetFrame (bpo-39947)
* PyThreadState_GetID (bpo-39947)
* PyThreadState_GetInterpreter (bpo-39947)

…when exiting via a finally block. (GH-23780)

* Make sure that return/break/continue are only traced once when exiting via a finally block.

* Add test for return in try-finally.

* Update importlib

…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

* 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

Fix freeze.py tool to use the prope config and library directories.

test_unix_events.py no longer checks if waitstatus_to_exitcode() mock
has been called or not to make the test more functional, rather than
checking the exact implementation.

Use shorter timeout and replace send() with sendall().

* 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.

Adding "stale" GitHub Action

Added the "stale" GitHub action to the CPython repo.
PR's older than 30 days will be labeled as stale using the "stale-pr" label.

Closes python/core-workflow#372

With this, we don't have to manually trigger backport whenever there is update to GitHub Actions dependencies.

GH-23783)

Enhance test_select.test_select(): it now takes 500 ms rather than 10
seconds.

* Use Python rather than a shell as the child process to make the
  test more portable.
* Use a sleep of 50 ms per line rather than 1 second.
* Use subprocess.Popen rather than os.popen().
