Rename namespace package __loader__ class to be public.
Make the old name, i.e. _NamespaceLoader, an alias for the public name, for backward compatibility.
An object implementing the os.PathLike protocol can represent a file
system path as a str or bytes object.
Therefore, _infer_return_type function should infer os.PathLike[str]
object as str type and os.PathLike[bytes] object as bytes type.
Also, reword the What's New messages: this doesn't change the limited API, it only brings the Py_LIMITED_API macro closer to the ideal of only allowing the limited API.

Since v8.6.11, a few configuration options seem to accept an empty value
where they did not previously; particularly the `type` of a `Menu`
widget, and the `compound` of any ttk widget with a label. Providing an
explicit expected error message to `checkEnumParam` bypasses the check
of an empty value, which no longer raises `TclError`.
Added non parallel-safe :func:`~contextlib.chdir` context manager to change
the current working directory and then restore it on exit. Simple wrapper
around :func:`~os.chdir`.

In Python 3.8 and 3.9, stacking `@functools.singledispatchmethod` on top of
`@classmethod` or `@staticmethod` caused an exception to be raised if the
method was registered using type-annotations rather than
`@method.register(int)`. This was not caught by unit tests, however, as the
tests only tested the `@method.register(int)` way of registering additional
implementations. The bug is no longer present in Python 3.10+, but
`test_functools.py` is still lacking regression tests for these cases. This
commit adds these test cases.
In gh-28954 I adjusted how test_embed determines if it should be skipped. That broke out-of-tree builds. This change fixes them.

There are two errors that this commit fixes:
* The parser was not correctly computing the offset and the string
source for E_LINECONT errors due to the incorrect usage of strtok().
* The parser was not correctly unwinding the call stack when a tokenizer
exception happened in rules involving optionals ('?', [...]) as we
always make them return valid results by using the comma operator. We
need to check first if we don't have an error before continuing.
* Generate test classes at import time. It allows to filter them when
run with unittest. E.g: "./python -m unittest test.test_dbm.TestCase_gnu -v".
* Create a database class in a new directory which will be removed after
test. It guarantees that all created files and directories be removed
and will not conflict with other dbm tests.
* Restore dbm._defaultmod after tests. Previously it was set to the last
dbm module (dbm.dumb) which affected other tests.
* Enable the whichdb test for dbm.dumb.
* Move test_keys to the correct test class. It does not test whichdb().
* Remove some outdated code and comments.
I considered only falling back when both were 0, but that still seems
wrong, and the highly popular rich[1] library does it this way, so I
thought we should probably inherit that behavior.

The Python 3.11 limited C API no longer includes stdlib.h, stdio.h,
string.h and errno.h.
* Exclude Py_MEMCPY() from Python 3.11 limited C API.
* xxlimited C extension is now built with Python 3.11 limited C API.
Move Include/longobject.h non-limited API to a new
Include/cpython/longobject.h header file.
Move the following definitions to the internal C API:
* _PyLong_DigitValue
* _PyLong_FormatAdvancedWriter()
* _PyLong_FormatWriter()
Split header files to move the non-limited API to Include/cpython/:
* Include/warnings.h => Include/cpython/warnings.h
* Include/weakrefobject.h => Include/cpython/weakrefobject.h
Exclude PyWeakref_GET_OBJECT() from the limited C API. It never
worked since the PyWeakReference structure is opaque in the limited C
API.
Move _PyWarnings_Init() and _PyErr_WarnUnawaitedCoroutine() to the
internal C API.
* bpo-45516: add protocol description to the Traversable documentation

* Avoid making C calls for most calls to Python functions.
* Change initialize_locals(steal=true) and _PyTuple_FromArraySteal to consume the argument references regardless of whether they succeed or fail.
