Flag members are now divided by one-bit verses multi-bit, with multi-bit being treated as aliases. Iterating over a flag only returns the contained single-bit flags.

Iterating, repr(), and str() show members in definition order.

When constructing combined-member flags, any extra integer values are either discarded (CONFORM), turned into ints (EJECT) or treated as errors (STRICT). Flag classes can specify which of those three behaviors is desired:

>>> class Test(Flag, boundary=CONFORM):
...     ONE = 1
...     TWO = 2
...
>>> Test(5)
<Test.ONE: 1>

Besides the three above behaviors, there is also KEEP, which should not be used unless necessary -- for example, _convert_ specifies KEEP as there are flag sets in the stdlib that are incomplete and/or inconsistent (e.g. ssl.Options). KEEP will, as the name suggests, keep all bits; however, iterating over a flag with extra bits will only return the canonical flags contained, not the extra bits.

Iteration is now in member definition order.  If member definition order
matches increasing value order, then a more efficient method of flag
decomposition is used; otherwise, sort() is called on the results of
that method to get definition order.


``re`` module:

repr() has been modified to support as closely as possible its previous
output; the big difference is that inverted flags cannot be output as
before because the inversion operation now always returns the comparable
positive result; i.e.

   re.A|re.I|re.M|re.S is ~(re.L|re.U|re.S|re.T|re.DEBUG)

in both of the above terms, the ``value`` is 282.

re's tests have been updated to reflect the modifications to repr().

* Rename _Py_module_names to _Py_stdlib_module_names.
* Rename Python/module_names.h to Python/stdlib_module_names.h.

…ctory changed (#23412)

This commit only adds tests and a news entry. The actual bug was fixed in the earlier commit.

)

Replace versionchanged markup with versionadded.

Add sys.module_names, containing the list of the standard library
module names.

Lowercase 'tkColorChooser', 'tkFileDialog', 'tkSimpleDialog', and
'tkMessageBox' and remove 'tk'.  Just lowercase 'tkFont' as 'font'
is already used.  Adjust import.

)

Previously it was an error with confusing error message.

Remove 9 remaining '(object)' occurrences in class headers in idlelib
and 25 '()' occurrences in idlelib.idle_test class headers.

@vstinner [noticed on python-dev](https://mail.python.org/archives/list/python-dev@python.org/thread/O3T7SK3BGMFWMLCQXDODZJSBL42AUWTR/) that there is no what's new or porting entry for removal of asyncio ``loop`` parameter. 

This patch adds a basic guide.

Add --with-wheel-pkg-dir=PATH option to the ./configure script. If
specified, the ensurepip module looks for setuptools and pip wheel
packages in this directory: if both are present, these wheel packages
are used instead of ensurepip bundled wheel packages.

Some Linux distribution packaging policies recommend against bundling
dependencies. For example, Fedora installs wheel packages in the
/usr/share/python-wheels/ directory and don't install the
ensurepip._bundled package.

ensurepip: Remove unused runpy import.
