Fix test_multiprocessing_main_handling: use multiprocessing.Pool with
a context manager and then explicitly join the pool.

Fix a race condition in check_interrupted_write() of test_io:
create directly the thread with SIGALRM signal blocked,
rather than blocking the signal later from the thread. Previously, it
was possible that the thread gets the signal before the signal is
blocked.

Add a comment explaining why system_alias() doesn't alias Darwin to
macOS.

check_environ() of distutils.utils now catchs KeyError on calling
pwd.getpwuid(): don't create the HOME environment variable in this
case.

Remove ctypes callback workaround: no longer create a callback at startup.
Avoid SELinux alert on "import ctypes" and "import uuid".

uuid.uuid1() now calls time.time_ns() rather than
int(time.time() * 1e9). Replace also int(nanoseconds/100)
with nanoseconds // 100. Add an unit test.

Rename test.bisect module to test.bisect_cmd to avoid conflict with
bisect module when running directly a test like
"./python Lib/test/test_xmlrpc.py".

Make platform.architecture() parsing of "file" command output more
reliable:

* Add the "-b" option to the "file" command to omit the filename;
* Force the usage of the C locale;
* Search also the "shared object" pattern.

I thought these simple changes doesn't need bpo number(Am I right..?).

Please refer to the commit message for detail.

bpo-23451, bpo-22117: Python 3.5 requires Windows Vista or newer,
time.monotonic() is now always system-wide.

TextTestRunner of unittest.runner now uses time.perf_counter() rather
than time.time() to measure the execution time of a test: time.time()
can go backwards, whereas time.perf_counter() is monotonic.

Similar change made in libregrtest, pprint and random.

Replace time.time() with time.monotonic() in tests to measure time
delta.

test_zipfile64: display progress every minute (60 secs) rather than
every 5 minutes (5*60 seconds).

platform.dist() is deprecated and slated for removal in Python 3.8. The
upload command itself should also not be used to upload to PyPI, but
while it continues to exist it should not use deprecated functions.

polish documentation for profile and resource modules

"make profile-opt" no longer replaces CFLAGS_NODIST with CFLAGS. It
now adds profile-guided optimization (PGO) flags to CFLAGS_NODIST,
existing CFLAGS_NODIST flags are kept.

Python 2.4 dropped MacOS 9 support. The macpath module was deprecated
in Python 3.7. This change removes it.

struct.calcsize('P') now always works.

bpo-34279, bpo-35412: support.run_unittest() no longer raises
TestDidNotRun if a test result contains skipped tests. The
exception is now only raised if no test have been run and no test
have been skipped.

* Add the pid and parent pid to multiprocessing.BaseProcess.__repr__().
* Add negative sign (ex: "-SIGTERM") to exitcode (process killed
  by a signal)
* Only call _popen.poll() once.

Example:
  <ForkProcess(ForkPoolWorker-1, started daemon)>
becomes:
  <ForkProcess name='ForkPoolWorker-1' pid=12449 parent=12448 started daemon>

Example:
  <ForkProcess(ForkPoolWorker-1, stopped[SIGTERM] daemon)>
becomes:
  <ForkProcess name='ForkPoolWorker-1' pid=12960 parent=12959 stopped exitcode=-SIGTERM daemon>

# Fixed missing colun in library/sys.po


[bpo-35492](https://bugs.python.org/issue35492): Fixed missing colun in library/sys.po

* Add multiprocessing.Pool.__repr__() to ease debug
* RUN, CLOSE and TERMINATE constants values are now strings rather
  than integer to ease debug

multiprocessing.Pool.__enter__() now fails if the pool is not
running: "with pool:" fails if used more than once.
