Fix command line parsing: reject "-X int_max_str_digits" option with
no value (invalid) when the PYTHONINTMAXSTRDIGITS environment
variable is set to a valid limit.
Only call tkinter.tk and its follow-up code in _init_tk_type when requires('gui')
does not raise. This function can be called as an unintended side-effect of
calling other idlelib code as part of tests on macOS without a GUI enabled.
The main problem was that an unluckily timed task cancellation could cause
the semaphore to be stuck. There were also doubts about strict FIFO ordering
of tasks allowed to pass.
The Semaphore implementation was rewritten to be more similar to Lock.
Many tests for edge cases (including cancellation) were added.
They were undertested, and since #96954 might involve a
rewrite of this part of the code we want to ensure that
there won't be any behavioral change.

This reverts commit 0587810698.
Reason: This broke buildbots (some warnings added by that commit are turned to errors in the SSL buildbot).
Repro: ./python Lib/test/ssltests.py
- Improve error message when parameter without a default follows one with a default
- Show same error message when positional-only params precede the default/non-default sequence
Warn on loop initialization, when setting the wakeup fd disturbs a previously set wakeup fd, and on loop closing, when upon resetting the wakeup fd, we find it has been changed by someone else.
Previously codeop.compile_command() emitted compiler warnings (SyntaxWarning or
DeprecationWarning) and raised a SyntaxError for incomplete input containing
a potentially incorrect code. Now it always returns None for incomplete input
without emitting any warnings.
* fix: annotate `pstats.FunctionProfile.ncalls` as `str`
This change aligns the type annotation of `pstats.FunctionProfile.ncalls` with its runtime type.
The test file, a modified version of Lib/test/audiodata/pluck-pcm24.wav, was provided by Andrea Celletti on the bug tracker.

A regression would still absolutely fail and even a flaky pass isn't
harmful as it'd fail most of the time across our N system test runs.
Windows has a low resolution timer and CI systems are prone to odd
timing so this just gives more leeway to avoid flakiness.
This makes tokenizer.c:valid_utf8 match stringlib/codecs.h:decode_utf8.
It also fixes an off-by-one error introduced in 3.10 for the line number when the tokenizer reports bad UTF8.
