Enable recursion checks which were disabled when get __bases__ of
non-type objects in issubclass() and isinstance() and when intern
strings. It fixes a stack overflow when getting __bases__ leads
to infinite recursion.
Originally recursion checks was disabled for PyDict_GetItem() which
silences all errors including the one raised in case of detected
recursion and can return incorrect result. But now the code uses
PyDict_GetItemWithError() and PyDict_SetDefault() instead.

bpo-41789: honor object overrides in Enum classes (GH-22250)
EnumMeta double-checks that `__repr__`, `__str__`, `__format__`, and `__reduce_ex__` are not the same as `object`'s, and replaces them if they are -- even if that replacement was intentionally done in the Enum being constructed. This patch fixes that.

[3.8] Improve asyncio-dev 'Concurrency and Multithreading' docs (GH-20882) (GH-22010)
I added some information to the `Concurrency and Multithreading` section of the `Developing with asyncio` guide.
This is all information that would have helped me when I started using asyncio. I incorrectly assumed that `loop.call_soon_threadsafe()` and `run_coroutine_threadsafe()` could be called from a thread in a process separate from the one that the event loop is running in. Explicitly stating that this will not work will probably help some people starting out with asyncio in the future.
I also added references to some other functions that can be used for inter-process communication without blocking the event loop. The section already mentions running blocking code in a ThreadPoolExecutor, but I think listing these other options in this section will also be helpful.

bpo-39010: Improve test shutdown (GH-22066) (#22083)
Simply closing the event loop isn't enough to avoid warnings. If we

logs a "dangling thread" warning.
bpo-39010: Fix errors logged on proactor loop restart (GH-22017) (#22035)
Stopping and restarting a proactor event loop on windows can lead to

to start multiple copies of the self-pipe reading loop.

[3.8] [3.9] bpo-41654: Fix deallocator of MemoryError to account for subclasses (GH-22020) (GH-22046)
When allocating MemoryError classes, there is some logic to use
pre-allocated instances in a freelist only if the type that is being
allocated is not a subclass of MemoryError. Unfortunately in the
destructor this logic is not present so the freelist is altered even
with subclasses of MemoryError..

[3.8] venv: Update Aspen URL in 'activate' script comment (GH-21797)
A comment in the venv `activate` script (as well as `activate.csh` and `activate.fish`) referencing Aspen magic directories lists a "further information" URL for Aspen at the zetadev.com website. zetadev.com changed ownership in 2019, and now redirects to a server in China with an expired security certificate.
Out of an abundance of caution, while not changing the _code_ for the activate scripts, this PR updates the URL in those comments to reference Aspen's new documentation home at https://aspen.io/.
No issue created, as I suspect this falls within the definition of a "trivial" change. Please let me know if I'm wrong about that, and I'll open the necessary issue(s).
While filed against the 3.8 branch, strictly speaking this is not a backported PR. The comment in question was entirely removed from the script between Python 3.8 and 3.9.
(IMHO this _should_ probably be backported to 3.7 and 3.6, as well. I'll happily file those PRs if needed.)
