Revert "gh-135410: use a critical section around `StringIO.__next__` (GH-135412)" (GH-135439)
This reverts commit e6c3039cb3.
(cherry picked from commit 73431356d3)
Co-authored-by: Peter Bierma <zintensitydev@gmail.com>
PEP-734 has been accepted (for 3.14).
(FTR, I'm opposed to putting this under the concurrent package, but
doing so is the SC condition under which the module can land in 3.14.)

We were incorrectly handling a few opcodes that leave their operands on the stack. Treat all of these conservatively; assume that they always leave operands on the stack.

On Windows, the `_PyOS_SigintEvent()` event handle is used to interrupt
the main thread when Ctrl-C is pressed. Previously, we also waited on
the event from other threads, but ignored the result. However, this can
race with interpreter shutdown because the main thread closes the handle
in `_PySignal_Fini` and threads may still be running and using mutexes
during interpreter shtudown.
Only use `_PyOS_SigintEvent()` in the main thread in parking_lot.c, like
we do in other places in the CPython codebase.

OpenSSL and HACL*-based hash functions constructors now support both `data` and `string` parameters.
Previously these constructor functions inconsistently supported sometimes `data` and sometimes `string`,
while the documentation expected `data` to be given in all cases.

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.

gh-133960: Improve typing.evaluate_forward_ref (GH-133961)
As explained in GH-133960, this removes most of the behavior differences with ForwardRef.evaluate.
The remaining difference is about recursive evaluation of forwardrefs; this is practically useful
in cases where an annotation refers to a type alias that itself is string-valued.
This also improves several edge cases that were previously not handled optimally. For example,
the function now takes advantage of the partial evaluation behavior of ForwardRef.evaluate() to
evaluate more ForwardRefs in the FORWARDREF format.
This also fixes GH-133959 as a side effect, because the buggy behavior in GH-133959 derives from
evaluate_forward_ref().
