* Add a preview for the "next release" change notes
This change integrates `sphinxcontrib-towncrier` into the docs build.
It uses Towncrier and its configs to render a draft changelog as RST
and injects that into the `changelog.rst` document right above the
older changelog entries using `towncrier-draft-entries` directive.
* Drop the change note from PR #1016
This partially reverts commit 0165dc355d2eb475cf59894d1561efb9b1963a39.
* Use `Not yet released` in the changelog draft

Unfortunately, I'm unable to run tests locally b/c of severe dependency
hell. I am unable to get tox, detox, python setup.py test, and other
means of running tests to work at all. So, since I'm blocked on a
project by the lack of optional validator support, I am going to close
my eyes, look away, and pull the trigger, and hope I hit the target.
If someone who has a working Python configuration can please be kind
enough to let me know if my changes fail any tests, I'd be very
appreciative.
Even better, I'd love to know why a stock Python distribution with
dependencies installed is incapable of running the tests for attrs.
However, this isn't the right forum to answer that question.
(This PR has the 17+ debugging commits cleaned up.)
