gh-124402: Speed up test_free_threading and test_super (#124491)
* Reduce the number of iterations and the number of threads so a
whole test file takes less than a minute.
* Refactor test_racing_iter_extend() to remove two levels of
indentation.
* test_monitoring() uses a sleep of 100 ms instead of 1 second.
gh-101100: Make __subclasses__ doctest stable (#124577)
Using a standard library class makes this test difficult to maintain
as other tests and other parts of the stdlib may create subclasses,
which may still be alive when this test runs depending on GC timing.
gh-123242: Note that type.__annotations__ may not exist (#124557)
Closes #123242. The real criterion is that the attribute does not
exist on heap types, but I don't think we should discuss heap vs.
static types in the language reference.

Make `versionchanged:: next`` expand to current (unreleased) version.
When a new CPython release is cut, the release manager will replace
all such occurences of "next" with the just-released version.

gh-119400: make_ssl_certs: update reference test data automatically, pass in expiration dates as parameters #119400 (GH-119401)
* Lib/test/certdata: do not hardcode reference cert data into tests
The script was simply printing the reference data and asking
users to update it by hand into the test suites. This can
be easily improved by writing the data into files and
having the test cases load the files.
* make_ssl_certs: make it possible to pass in expiration dates from command line
Note that in this commit, the defaults are same as they were,
so if nothing is specified the script works as before.

gh-119180: Avoid going through AST and eval() when possible in annotationlib (#124337)
Often, ForwardRefs represent a single simple name. In that case, we
can avoid going through the overhead of creating AST nodes and code
objects and calling eval(): we can simply look up the name directly
in the relevant namespaces.

typing.get_origin() does what we need here, without reaching into
typing internals. This shouldn't change any behavior (so I am going
to skip news), but it sets a good example for other users introspecting
typing objects.

gh-119180: Fix annotationlib.ForwardRef.evaluate with no globals (#124326)
We were sometimes passing None as the globals argument to eval(), which makes it
inherit the globals from the calling scope. Instead, ensure that globals is always
non-None. The test was passing accidentally because I passed "annotationlib" as a

two unused private ones.

GH-113655: Lower the C recursion limit for HPPA, PPC64 and SPARC (#124264)
Lower the C recursion limit for HPPA, PPC64 and SPARC, as they use
relatively large stack frames that cause e.g. `test_descr` to hit
a stack overflow. According to quick testing, it seems that values
around 8000 are max for HPPA and PPC64 (ELFv1 ABI) and 7000 for SPARC64.
To keep things safe, let's use 5000 for PPC64 and 4000 for SPARC.

gh-112938: IDLE - Fix uninteruptable hang when Shell gets rapid continuous output. (#124310)
https://github.com/python/cpython/issues/88496 replaced text.update with text.update_idletasks in colorizer.py and outwin.py to fix test failures on macOS. While theoretically correct, the result was Shell freezing when receiving continuous short strings to print. Test: `while 1: 1`.
The guess is that there is no idle time in which to do the screen update. Reverting the change in one of the files,
outwin, fixes the issue. Colorizer runs ever 1/20 second and seems to work fine.
When running test-outwin on macOS, alias 'update'
to 'update_idletasks on the text used for testing.
Add a helper function that checks whether the test suite is running
inside a systemd-nspawn container, and skip the few tests failing
with `--suppress-sync=true` in that case. The tests are failing because
`--suppress-sync=true` stubs out `fsync()`, `fdatasync()` and `msync()`
calls, and therefore they always return success without checking for
invalid arguments.
Call `os.open(__file__, os.O_RDONLY | os.O_SYNC)` and check the errno to
detect whether `--suppress-sync=true` is actually used, and skip
the tests only in that scenario.
