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.
Linux abstract sockets are insecure as they lack any form of filesystem
permissions so their use allows anyone on the system to inject code into
the process.
This removes the default preference for abstract sockets in
multiprocessing introduced in Python 3.9+ via
https://github.com/python/cpython/pull/18866 while fixing
https://github.com/python/cpython/issues/84031.
Explicit use of an abstract socket by a user now generates a
RuntimeWarning. If we choose to keep this warning, it should be
backported to the 3.7 and 3.8 branches.
* The compiler analyzes the usage of the first 64 local variables all at once using bit masks.
* Local variables beyond the first 64 are only partially analyzed, achieving linear time.
Work on test coverage for `PyObject_Print` made it clear that some lines can't get executed.
Simplify the function by excluding the checks for non-string types.
Also eliminate creating a temporary bytes object.
Added os.setns and os.unshare to easily switch between namespaces
on Linux.

Make sys.setprofile() and sys.settrace() functions reentrant. They
can no long fail with: RuntimeError("Cannot install a trace function
while another trace function is being installed").
Make _PyEval_SetTrace() and _PyEval_SetProfile() functions reentrant,
rather than detecting and rejecting reentrant calls. Only delete the
reference to function arguments once the new function is fully set,
when a reentrant call is safe. Call also _PySys_Audit() earlier.
Rely on the title of the linked internal page instead of putting the title. Sphinx will render with the title correctly, and this will reduce work for translators
* Link ZipFile in What's New entry discussing it
* Add entry for new ZipFile.mkdir method
* Add entry for new zipfile.Path.stem/suffix/suffixes methods
* Add missing line breaks between zipfile bullet list items
* Add entry for new logging.getLevelNamesMapping function
* Add entry for SysLogHandler.createSocket to whatsnew
* Add missing line break between logging bullet list items
