* fix auto() failure during multiple assignment
i.e. `ONE = auto(), 'text'` will now have `ONE' with the value of `(1,
'text')`. Before it would have been `(<an auto instance>, 'text')`

The test.support.wait_process() function now uses a timeout of
LONG_TIMEOUT seconds by default, instead of SHORT_TIMEOUT. It
doesn't matter if a Python buildbot is slower, it only matters that
the process completes. The timeout should just be shorter than
"forever".

In very rare circumstances the JUMP opcode could be confused with the
argument of the opcode in the "then" part which doesn't end with the
JUMP opcode. This led to incorrect detection of the final JUMP opcode
and incorrect calculation of the size of the subexpression.
NOTE: Changed return value of functions _validate_inner() and
_validate_charset() in Modules/_sre/sre.c. Now they return 0 on success,
-1 on failure, and 1 if the last op is JUMP (which usually is a failure).
Previously they returned 1 on success and 0 on failure.

The uuid.getnode() function has multiple implementations, tested sequentially.
The ifconfig implementation was incorrect and always failed: fix it.
In practice, functions of libuuid library are preferred, if available:
uuid_generate_time_safe(), uuid_create() or uuid_generate_time().

* gh-98925: Lower marshal recursion depth for WASI (GH-98938)
For wasmtime 2.0, the stack depth cost is 6% higher. This causes the default max `marshal` recursion depth to blow the stack.
As the default marshal depth is 2000 and Windows is set to 1000, split the difference and choose 1500 for WASI to be safe.

Fix subscription of type aliases containing bare generic types or types
like TypeVar: for example tuple[A, T][int] and tuple[TypeVar, T][int],
where A is a generic type, and T is a type variable.

* As most of `test_embed` now uses `Py_InitializeFromConfig`, add
a specific test case to cover `Py_Initialize` (and `Py_InitializeEx`)
* Rename `_testembed` init helper to clarify the API used
* Add a `PyConfig_Clear` call in `Py_InitializeEx` to make
the code more obviously correct (it already didn't leak as
none of the dynamically allocated config fields were being
populated, but it's clearer if the wrappers follow the
documented API usage guidelines)

On Windows, when the Python test suite is run with the -jN option,
the ANSI code page is now used as the encoding for the stdout
temporary file, rather than using UTF-8 which can lead to decoding
errors.

Fix multiplying a list by an integer (list *= int): detect the
integer overflow when the new allocated length is close to the
maximum size. Issue reported by Jordan Limor.
list_resize() now checks for integer overflow before multiplying the
new allocated length by the list item size (sizeof(PyObject*)).

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.

The macOS 13 SDK includes support for the `mkfifoat` and `mknodat` system calls.
Using the `dir_fd` option with either `os.mkfifo` or `os.mknod` could result in a
segfault if cpython is built with the macOS 13 SDK but run on an earlier
version of macOS. Prevent this by adding runtime support for detection of
these system calls ("weaklinking") as is done for other newer syscalls on
macOS.
