bpo-37137: Fix test_asyncio: use TestCase.set_event_loop() (GH-13779)
Replace asyncio.set_event_loop() with TestCase.set_event_loop() of
test_asyncio.utils: this method calls TestCase.close_loop() which
waits until the executor completes, to avoid leaking dangling
threads.
Inherit from test_asyncio.utils.TestCase rather than
unittest.TestCase.

Modify test_coroutines, test_cprofile, test_generators, test_raise,
test_ssl and test_yield_from to use
support.catch_unraisable_exception() rather than
support.captured_stderr().
test_thread: remove test_save_exception_state_on_error() which is now
updated. test_unraisable_exception() checks that sys.unraisablehook()
is called to handle _thread.start_new_thread() exception.
test_cprofile now rely on unittest for test discovery: replace
support.run_unittest() with unittest.main().

bpo-36974: Make tp_call=PyVectorcall_Call work for inherited types (GH-13699)
When inheriting a heap subclass from a vectorcall class that sets
`.tp_call=PyVectorcall_Call` (as recommended in PEP 590), the subclass does
not inherit `_Py_TPFLAGS_HAVE_VECTORCALL`, and thus `PyVectorcall_Call` does
not work for it.
This attempts to solve the issue by:
* always inheriting `tp_vectorcall_offset` unless `tp_call` is overridden
in the subclass
* inheriting _Py_TPFLAGS_HAVE_VECTORCALL for static types, unless `tp_call`
is overridden
* making `PyVectorcall_Call` ignore `_Py_TPFLAGS_HAVE_VECTORCALL`
This means it'll be ever more important to only call `PyVectorcall_Call`
on classes that support vectorcall. In `PyVectorcall_Call`'s intended role
as `tp_call` filler, that's not a problem.

bpo-36813: Fix QueueListener to call task_done() upon termination. (GH-13113)
Fixed QueueListener in order to avoid random deadlocks.
Unable to add regression tests atm due to time constraints, will add it in a bit.
Regarding implementation, although it's nested, it does not cause performance issues whatsoever, and does not call task_done() in case of an exception (which is the right thing to do IMHO).

Adds a new option in trace that allows tracing runnable modules. It is

bpo-37029: keep usable_arenas in sorted order without searching (#13612)
This adds a vector of "search fingers" so that usable_arenas can be kept in sorted order (by number of free pools) via constant-time operations instead of linear search.
This should reduce worst-case time for reclaiming a great many objects from O(A**2) to O(A), where A is the number of arenas. See bpo-37029.

The ssl module now can dump key material to a keylog file and trace TLS

The msg_callback and related enums are private members. The feature

bpo-29262: Add get_origin() and get_args() introspection helpers to typing (GH-13685)
This is an old feature request that appears from time to time. After a year of experimenting with various introspection capabilities in `typing_inspect` on PyPI, I propose to add these two most commonly used functions: `get_origin()` and `get_args()`. These are essentially thin public wrappers around private APIs: `__origin__` and `__args__`.
As discussed in the issue and on the typing tracker, exposing some public helpers instead of `__origin__` and `__args__` directly will give us more flexibility if we will decide to update the internal representation, while still maintaining backwards compatibility.
The implementation is very simple an is essentially a copy from `typing_inspect` with one exception: `ClassVar` was special-cased in `typing_inspect`, but I think this special-casing doesn't really help and only makes things more complicated.
As per the PEP and the [audit event raised](https://github.com/python/cpython/blob/13d4e6a4a090031f8214e058ed3c8fd47767e05f/Lib/urllib/request.py#L524) in urllib.request this should be `urllib.Request`
