gh-90155: Fix bug in asyncio.Semaphore and strengthen FIFO guarantee (#93222) 
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.

gh-96954: Add tests for unicodedata.name/lookup (#96955) 
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.

gh-96947: Fix comment on `pyruntimestate->pyinterpreters` struct for `next_id` (GH-96949) 
`_next_interp_id` appeared on [this commit](e377416c10 (diff-7ac11e526f79b42d6ea9d3592cb99da46775640c69fa5510f4a6de87cced7141R68)) renamed to `next_id` ([by this commit](2ebc5ce42a (diff-bccfc01bd96b58c022dde77486b8a896cbb31d7581bd4a4156b32c3654afe468R59))). 

Also, now, `next_id` gets initialized in` _PyInterpreterState_Enable()` 12c5f328d2/Python/pystate.c (L241-L244) because `_PyInterpreterState_Init()` function doesn't exist at all.

gh-96387: take_gil() resets drop request before exit (#96869) 
At Python exit, sometimes a thread holding the GIL can wait forever
for a thread (usually a daemon thread) which requested to drop the
GIL, whereas the thread already exited. To fix the race condition,
the thread which requested the GIL drop now resets its request before
exiting.

take_gil() now calls RESET_GIL_DROP_REQUEST() before
PyThread_exit_thread() if it called SET_GIL_DROP_REQUEST to fix a
race condition with drop_gil().

Issue discovered and analyzed by Mingliang ZHAO.

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.
