Before Python 3.6, os.path.abspath(None) used to report an AttributeError which was properly caught inside site.abs_paths, making it ignore __main__, one of sys.modules, which has __file__ and __cached__ set to None. With 3.6, os.path.abspath(None) raises TypeError instead which site.abs_path was not expecting. This resulted in an uncaught exception if a user had PYTHONSTARTUP set and the application called site.main() which a number of third-party programs do.

A datetime object d is aware if d.tzinfo is not None and
d.tzinfo.utcoffset(d) does not return None. If d.tzinfo is None,
or if d.tzinfo is not None but d.tzinfo.utcoffset(d) returns None,
d is naive.
This commit ensures that instances with non-None d.tzinfo, but
d.tzinfo.utcoffset(d) returning None are treated as naive.
In addition, C acceleration code will raise TypeError if
d.tzinfo.utcoffset(d) returns an object with the type other than
timedelta.
* Updated the documentation.
Assume that the term "naive" is defined elsewhere and remove the
not entirely correct clarification. Thanks, Tim.

If tests are re-run, use "xxx then yyy" result format (ex: "FAILURE
then SUCCESS") to show that some failing tests have been re-run.
Add also test_regrtest.test_rerun_fail() test.

While locale coercion and UTF-8 mode turned out to
be complementary ideas rather than competing ones,
it isn't immediately obvious why it's useful to
have both, or how they interact at runtime.
This updates both the Python 3.7 What's New doc
and the PYTHONCOERCECLOCALE and PYTHONUTF8
documentation in an attempt to clarify that
relationship:
- in the respective What's New sections, add a closing paragraph
explaining which problem each one solves, and pointing to the
other PEP's section for the specific aspects it relies on the other
PEP to solve
- use "locale-aware mode" as a more descriptive term for the
default non-UTF-8 mode
- improve wording conistenccy between the PYTHONCOERCECLOCALE
and PYTHONUTF8 docs when they cover the same thing (mostly
related to legacy locale detection and setting the standard
stream error handler)
- improve the description of the locale coercion trigger conditions
(including pointing out that setting LC_ALL turns off locale coercion)
- port the full description of the UTF-8 mode behaviour changes
from PEP 540 into the PYTHONUTF8 documentation
- be explicit that PYTHONIOENCODING still overrides the settings
for the standard streams
- mention concrete examples of things that do and don't get their
text encoding assumptions adjusted by the two text encoding
assumption override techniques

* Added a test case for strftime("%z").
The added test checks a case with UTC offest expressed in an integer
number of seconds.
* Added a test comparing naive and aware datetimes.
Check that a greater than comparison of a naive datetime instance with
an aware one raises a TypeError.
* Test datetime in fold or in gap comparison both ways.

The cancellation of an overlapped WSARecv() has a race condition
which causes data loss because of the current implementation of
proactor in asyncio.
No longer cancel overlapped WSARecv() in _ProactorReadPipeTransport
to work around the race condition.
Remove the optimized recv_into() implementation to get simple
implementation of pause_reading() using the single _pending_data
attribute.
Move _feed_data_to_bufferred_proto() to protocols.py.
Remove set_protocol() method which became useless.

Substract one because listdir() opens internally a file
