This reverts commit 82b5f6b.

The change broke the backwards compatibility of parsing behavior in a
patch release of Python (3.7.6). A decision was taken to revert this
patch in 3.7.7.

In https://bugs.python.org/issue27657 it was decided that the previous
behavior like

>>> urlparse('localhost:8080')
ParseResult(scheme='', netloc='', path='localhost:8080', params='', query='', fragment='')

>>> urlparse('undefined:8080')
ParseResult(scheme='', netloc='', path='undefined:8080', params='', query='', fragment='')

needs to be preserved in patch releases as number of users rely upon it.

Explicitly mention the releases involved with the revert in NEWS.
Adopt the wording suggested by @ned-deily.

The fix for [bpo-39386](https://bugs.python.org/issue39386) attempted to make it so you couldn't reuse a
agen.aclose() coroutine object. It accidentally also prevented you
from calling aclose() at all on an async generator that was already
closed or exhausted. This commit fixes it so we're only blocking the
actually illegal cases, while allowing the legal cases.

The new tests failed before this patch. Also confirmed that this fixes
the test failures we were seeing in Trio with Python dev builds:
  python-trio/trio#1396

bpo-21016, bpo-1294959: The pydoc and trace modules now use the
sysconfig module to get the path to the Python standard library, to
support uncommon installation path like /usr/lib64/python3.9/ on
Fedora.

Reflecting changes to the code, removed weakref.ReferenceError from weakref.rst and exceptions.rst.

Issue submitter provided evidence that the `weakref.ReferenceError` alias for `ReferenceError` was removed from the code in 2007.  Working with @gvanrossum at PyCascades CPython sprint we looked at the code and confirmed that `weakref.ReferenceError` was no longer in `weakref.py`.

Based on that analysis I removed references `weakref.ReferenceError` from the two documents where it was still being referenced: `weakref.rst` and `exceptions.rst`.

Some numerator types used (specifically NumPy) decides to not

call to bool() guarantees a bool return also for such types.

When called on a closed object, readinto() segfaults on account
of a write to a freed buffer:

    ==220553== Process terminating with default action of signal 11 (SIGSEGV): dumping core
    ==220553==  Access not within mapped region at address 0x2A
    ==220553==    at 0x48408A0: memmove (vg_replace_strmem.c:1272)
    ==220553==    by 0x58DB0C: _buffered_readinto_generic (bufferedio.c:972)
    ==220553==    by 0x58DCBA: _io__Buffered_readinto_impl (bufferedio.c:1053)
    ==220553==    by 0x58DCBA: _io__Buffered_readinto (bufferedio.c.h:253)

Reproducer:

    reader = open ("/dev/zero", "rb")
    _void  = reader.read (42)
    reader.close ()
    reader.readinto (bytearray (42)) GH-GH-GH- BANG!

The problem exists since 2012 when commit dc46945 added code
to free the read buffer on close().

Replace check for whether something is a method in the mock module. The
previous version fails on PyPy, because there no method wrappers exist
(everything looks like a regular Python-defined function). Thus the
isinstance(getattr(result, '__get__', None), MethodWrapperTypes) check
returns True for any descriptor, not just methods.

This condition could also return erroneously True in CPython for
C-defined descriptors.

Instead to decide whether something is a method, just check directly
whether it's a function defined on the class. This passes all tests on
CPython and fixes the bug on PyPy.
