Contrary to the current docs, ast.Constant will never hold containers
such as frozenset or tuple; the Python parser only emits it for simple
literals.
For precision, add the exact list of types that may be contained in an
ast.Constant.

gh-132775: Fix _PyFunctIon_VerifyStateless() ()
The problem we're fixing here is that we were using PyDict_Size() on "defaults",
which it is actually a tuple. We're also adding some explicit type checks.
This is a follow-up to gh-133221/gh-133528.

This adds a warning about the possibly-missing NUL terminator, but in a way
that doesn't make it sound like a bug/wart.

gh-133711: Fix test_regrtest for PYTHONUTF8=1 (GH-134839)
Use "backslashreplace" error handler to decode stdout and stderr.
Example:
vstinner@WIN C:\victor\python\main\build\test_python_worker_8360\x91>
"C:\victor\python\main\PCbuild\amd64\python_d.exe" -m test
--fast-ci --slow-ci --testdir
C:\Users\vstinner\AppData\Local\Temp\tmp0t59e8da
test_regrtest_noop1 test_regrtest_noop2 test_regrtest_noop3
test_regrtest_noop4
Notice the "\x91" byte at the end of the first line: it's the
non-ASCII U+00E6 character encoded to the OEM cp437 code page.

Fix typing.TYPE_CHECKING docs to reflect PEP 649. (GH-134813)
typing.TYPE_CHECKING should no longer steer users towards

gh-119180: Updates to PEP 649/749 docs (GH-134640)
- Mention (again) that `type.__annotations__` is unsafe. It is now safe
when using only classes defined under PEP 649 semantics, but not with
classes defined using `from __future__ import annotations`.
- Mention that annotations on instances no longer work. There was already
an issue about this.
- Mention the general changes in the "Porting to Python 3.14" section.
- `annotationlib` was proposed by PEP-749, not PEP-649.

gh-132493: Remove __annotations__ usage in inspect._signature_is_functionlike (GH-133415)
This check is potentially problematic because it could force evaluation of
annotations unnecessarily. This doesn't trigger for builtin objects (functions,
classes, or modules) with annotations, but it could trigger for third-party objects.
The check was not particularly useful anyway, because it succeeds if ``__annotations__``
is a dict or None, so the only thing this did was guard against objects that have an
``__annotations__`` attribute that is of some other type. That doesn't seem particularly
useful, so I just removed the check.
