Fix bugs where exceptions could end up being overwritten
because of deferred error handling.

When inverting a Flag member (or boundary STRICT), only consider other canonical flags; when inverting an IntFlag member (or boundary KEEP), also consider aliases.
* support inspect.iscoroutinefunction in create_autospec(async_def)
* test create_autospec with inspect.iscoroutine and inspect.iscoroutinefunction
* test when create_autospec functions check their signature
The original name wasn't as clear as it could have been. This change includes the following:
* rename the function
* change the default value for "disable_check" to False
* add clues to the docstring that folks should probably not use the function

This ensures that `commoninstall` is completed before `bininstall` is
started when parallel builds are used (`make -j install`), and so the
`python3` symlink is only installed after all standard library modules
are installed.

This commit introduces a 'walk-and-match' strategy for handling glob patterns that include a non-terminal `**` wildcard, such as `**/*.py`. For this example, the previous implementation recursively walked directories using `os.scandir()` when it expanded the `**` component, and then **scanned those same directories again** when expanded the `*.py` component. This is wasteful.
In the new implementation, any components following a `**` wildcard are used to build a `re.Pattern` object, which is used to filter the results of the recursive walk. A pattern like `**/*.py` uses half the number of `os.scandir()` calls; a pattern like `**/*/*.py` a third, etc.
This new algorithm does not apply if either:
1. The *follow_symlinks* argument is set to `None` (its default), or
2. The pattern contains `..` components.
In these cases we fall back to the old implementation.
This commit also replaces selector classes with selector functions. These generators directly yield results rather calling through to their successors. A new internal `Path._glob()` method takes care to chain these generators together, which simplifies the lazy algorithm and slightly improves performance. It should also be easier to understand and maintain.
When Python is built in debug mode (if the Py_REF_DEBUG macro is
defined), the Py_INCREF() and Py_DECREF() function are now always
implemented as opaque functions to avoid leaking implementation
details like the "_Py_RefTotal" variable or the
_Py_DecRefTotal_DO_NOT_USE_THIS() function.
* Remove _Py_IncRefTotal_DO_NOT_USE_THIS() and
_Py_DecRefTotal_DO_NOT_USE_THIS() from the stable ABI.
* Remove _Py_NegativeRefcount() from limited C API.
Disallow thread creation and fork at interpreter finalization.
in the following functions, check if interpreter is finalizing and raise `RuntimeError` with appropriate message:
* `_thread.start_new_thread` and thus `threading`
* `posix.fork`
* `posix.fork1`
* `posix.forkpty`
* `_posixsubprocess.fork_exec` when a `preexec_fn=` is supplied.

Upgrade builds to OpenSSL 1.1.1u.
This OpenSSL version addresses a pile if less-urgent CVEs since 1.1.1t.
The Mac/BuildScript/build-installer.py was already updated.
Also updates _ssl_data_111.h from OpenSSL 1.1.1u, _ssl_data_300.h from 3.0.9, and adds a new _ssl_data_31.h file from 3.1.1 along with the ssl.c code to use it.
Manual edits to the _ssl_data_300.h file prevent it from removing any existing definitions in case those exist in some peoples builds and were important (avoiding regressions during backporting).
backports of this prior to 3.12 will not include the openssl 3.1 header.
Remove functions in the C API:
* PyEval_AcquireLock()
* PyEval_ReleaseLock()
* PyEval_InitThreads()
* PyEval_ThreadsInitialized()
But keep these functions in the stable ABI.
Mention "make regen-limited-abi" in "make regen-all".
Remove the following old functions to configure the Python
initialization, deprecated in Python 3.11:
* PySys_AddWarnOptionUnicode()
* PySys_AddWarnOption()
* PySys_AddXOption()
* PySys_HasWarnOptions()
* PySys_SetArgvEx()
* PySys_SetArgv()
* PySys_SetPath()
* Py_SetPath()
* Py_SetProgramName()
* Py_SetPythonHome()
* Py_SetStandardStreamEncoding()
* _Py_SetProgramFullPath()
Most of these functions are kept in the stable ABI, except:
* Py_SetStandardStreamEncoding()
* _Py_SetProgramFullPath()
Update Doc/extending/embedding.rst and Doc/extending/extending.rst to
use the new PyConfig API.
_testembed.c:
* check_stdio_details() now sets stdio_encoding and stdio_errors
of PyConfig.
* Add definitions of functions removed from the API but kept in the
stable ABI.
* test_init_from_config() and test_init_read_set() now use
PyConfig_SetString() instead of PyConfig_SetBytesString().
Remove _Py_ClearStandardStreamEncoding() internal function.
Deprecate the old Py_UNICODE and PY_UNICODE_TYPE types in the C API:
use wchar_t instead.
Replace Py_UNICODE with wchar_t in multiple C files.

In gh-103912 we added tp_bases and tp_mro to each PyInterpreterState.types.builtins entry. However, doing so ignored the fact that both PyTypeObject fields are public API, and not documented as internal (as opposed to tp_subclasses). We address that here by reverting back to shared objects, making them immortal in the process.
`PurePath.match()` now handles the `**` wildcard as in `Path.glob()`, i.e. it matches any number of path segments.
We now compile a `re.Pattern` object for the entire pattern. This is made more difficult by `fnmatch` not treating directory separators as special when evaluating wildcards (`*`, `?`, etc), and so we arrange the path parts onto separate *lines* in a string, and ensure we don't set `re.DOTALL`.

Add a keyword-only *follow_symlinks* parameter to `pathlib.Path.glob()` and`rglob()`.
When *follow_symlinks* is `None` (the default), these methods follow symlinks except when evaluating "`**`" wildcards. When set to true or false, symlinks are always or never followed, respectively.
For backwards compatibility, accept backslashes as path separators in
`PurePosixPath` if an instance of `PureWindowsPath` is supplied.
This restores behaviour from Python 3.11.

Use `str.lower()` rather than `ntpath.normcase()` to normalize case of
Windows paths. This restores behaviour from Python 3.11.

* Remove the Lib/test/imghdrdata/ directory.
* Copy 5 pictures (gif, png, ppm, pgm, xbm) from removed
Lib/test/imghdrdata/ to a new Lib/test/tkinterdata/ directory.
* Update Sphinx from 4.5 to 6.2 in Doc/requirements.txt.
Reduced _idle_semaphore.release calls in concurrent.futures.thread._worker
_idle_semaphore.release() is now only called if only work_queue is empty.
