* bpo-1198569: Allow the braced pattern to be different

``string.Template`` subclasses can optionally define ``braceidpattern`` if
they want to specify different placeholder patterns inside and outside the
braces.  If None (the default) it falls back to ``idpattern``.

Blurbify master branch.

Patch by Paul.j3.  Includes an unrelated but useful addition to the
optparse porting section.

* Change code owners for hashlib and ssl to the crypto team

* Include the core CSPRNG for the crypto-team

Fix fileinput with inplace=True to accept pathlib.Path objects.

We never actually check HAVE_SELECT.

This is a required feature is C99, which we require.

Used in macOS framework builds.

Store exceptions as string rather than object to prevent reference
cycles which cause leaking dangling threads.

Call doCleanups() to close the loop after calling
executor.shutdown(wait=True): see TestCase.set_event_loop() of
asyncio.test_utils.

Replace also gc.collect() with support.gc_collect().

* bpo-31326: ProcessPoolExecutor waits for the call queue thread

concurrent.futures.ProcessPoolExecutor.shutdown() now explicitly
closes the call queue. Moreover, shutdown(wait=True) now also join
the call queue thread, to prevent leaking a dangling thread.

* Fix for shutdown() being called twice.

bpo-27144: concurrent.futures as_complete and map iterators do not keep reference to returned object (#1560)

* bpo-27144: concurrent.futures as_complie and map iterators do not keep
reference to returned object

* Some nits.  Improve wordings in docstrings and comments, and avoid relying on
sys.getrefcount() in tests.

* Explicitly call shutdown(wait=True) on executors to wait until all
  threads complete to prevent side effects between tests.
* Fix test_loop_self_reading_exception(): don't mock loop.close().
  Previously, the original close() method was called rather than the
  mock, because how set_event_loop() registered loop.close().

Use a pool of integer objects toprevent false alarm when checking for
memory block leaks. Fill the pool with values in -1000..1000 which
are the most common (reference, memory block, file descriptor)
differences.

Use base class rather than metaclass in examples.

Update old devguide links from https://docs.python.org/devguide to https://devguide.python.org

Code was indented with three spaces.
Fixed using four spaces.

* Fixes #30581 by adding a path to use newer GetMaximumProcessorCount API on Windows calls to os.cpu_count()

* Add NEWS.d entry for bpo-30581, os.cpu_count on Windows.

* Tweak NEWS entry

* Make error message more informative

Replace assertions in error-reporting code with more-informative version that doesn't cause confusion over where and what the error is.

* Additional clarification + get travis to check

* Change from SystemError to TypeError

As suggested in PR comment by @pitrou, changing from SystemError; TypeError appears appropriate.

* NEWS file installation; ACKS addition (will do my best to justify it by additional work)

* Making current AssertionErrors in multiprocessing more informative

* Blurb added re multiprocessing managers.py, queues.py cleanup

* Further multiprocessing cleanup - went through pool.py

* Fix two asserts in multiprocessing/util.py

* Most asserts in multiprocessing more informative

* Didn't save right version

* Further work on multiprocessing error messages

* Correct typo

* Correct typo v2

* Blasted colon... serves me right for trying to work on two things at once

* Simplify NEWS entry

* Update 2017-08-18-17-16-38.bpo-5001.gwnthq.rst

* Update 2017-08-18-17-16-38.bpo-5001.gwnthq.rst

OK, never mind.

* Corrected (thanks to pitrou) error messages for notify

* Remove extraneous backslash in docstring.

if pathname.replace('/', '\\') returns non-string.
