`list(sys.modules.items())` was apparently not immune to "dictionary
changed size during iteration" errors.
Tested internally using an integration test that has run into this a couple of times in the past two years. With this patch applied, the test is no longer flaky.

Fix compileall.compile_dir() ddir= behavior on sub-packages.
Fixes compileall.compile_dir's ddir parameter and compileall command
line flag `-d` to no longer write the wrong pathname to the generated
pyc file for submodules beneath the root of the directory tree being
compiled. This fixes a regression introduced with Python 3.5.
Tests backported from GH 02673352b5, the
implementation is different due to intervening code changes. But still
quiet simple.
Why was the bug ever introduced? The refactoring to add parallel
execution kept the ddir -> dfile computations but discarded the results
instead of sending them to compile_file(). This fixes that. Lack of tests
meant this went unnoticed.
* bpo-39548: Fix handling of 'WWW-Authenticate' header for Digest authentication
- The 'qop' value in the 'WWW-Authenticate' header is optional. The
presence of 'qop' in the header should be checked before its value

When `allow_abbrev` was first added, disabling the abbreviation of
long options broke the grouping of short flags ([bpo-26967](https://bugs.python.org/issue26967)). As a fix,
b1e4d1b603 (contained in v3.8) ignores `allow_abbrev=False` for a
given argument string if the string does _not_ start with "--"
(i.e. it doesn't look like a long option).
This fix, however, doesn't take into account that long options can
start with alternative characters specified via `prefix_chars`,
introducing a regression: `allow_abbrev=False` has no effect on long
options that start with an alternative prefix character.
The most minimal fix would be to replace the "starts with --" check
with a "starts with two prefix_chars characters". But
`_get_option_tuples` already distinguishes between long and short
options, so let's instead piggyback off of that check by moving the
`allow_abbrev` condition into `_get_option_tuples`.

This reverts commit 0f3187c1ce.
The change broke the backwards compatibility of parsing behavior in a
patch release of Python (3.8.1). A decision was taken to revert this
patch in 3.8.2.
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.
Setting `-D_XOPEN_SOURCE=700` on HP-UX causes system functions such as chroot to be undefined. This change stops `_XOPEN_SOURCE` begin set on HP-UX

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:
