Updated py-twisted to 16.5.0.

Twisted Core 16.5.0 (2016-10-28)
================================

Features
--------
- Added twisted.internet.defer.Deferred.addTimeout method to enable
  timeouts of deferreds. (#5786)
- Perspective Broker (the twisted.spread package) has been ported to
  Python 3 (#7598)
- 'yield from' can now be used on Deferreds inside generators, when
  the generator is wrapped with
  twisted.internet.defer.ensureDeferred. (#8087)
- twisted.internet.asyncioreactor has been added, which is a Twisted
  reactor on top of Python 3.4+'s native asyncio reactor. It can be
  selected by passing "--reactor=asyncio" to Twisted tools (twistd,
  Trial, etc) on platforms that support it (Python 3.4+). (#8367)
- twisted.python.zippath now works on Windows with Python 3. (#8747)
- twisted.internet.cfreactor is ported to Python 3 and supported on
  2.7 and 3.5+. (#8838)

Bugfixes
--------
- twisted.internet.test.test_iocp and twisted.internet.test.test_tcp
  have been fixed to work under Python 3 with the Windows IOCP
  reactor (#8631)
- Arguments to processes on Windows are now passed mbcs-encoded
  arguments.  This prevents process-related tests from hanging on
  Windows with Python 3. (#8735)
- Client and server TLS connections made via the client TLS endpoint
  and the server SSL endpoint, as well as any other code that uses
  twisted.internet.ssl.CertificateOptions, no longer accept 3DES-
  based cipher suites by default, to defend against SWEET32. (#8781)
- twisted.logger.jsonFileLogObserver no longer emits non-JSON
  tracebacks into its file; additionally,
  twisted.logger.formatEventAsClassicLogText now includes traceback
  information for the log event it formats. (#8858)
- twisted.python.version now exports a version of Incremental that is
  16.10.1 or higher, making t.p.v.Version package name comparisons
  case-insensitive. (#8863)
- twisted.python.reflect.safe_str encodes unicode as ascii with
  backslashreplace error handling on Python 2. (#8864)

Improved Documentation
----------------------
- The twisted.internet.interfaces.IProtocol.dataReceived() method
  takes one parameter of type bytes.  This has been clarified in the
  doc string. (#8763)

Deprecations and Removals
-------------------------
- twisted.python.constants is deprecated in preference to constantly
  on PyPI, which is the same code rolled into its own package.
  (#7351)
- twisted.python.dist3 has been made private API. (#8761)
- When the source code is checked out, bin/trial is no longer in the
  tree.  Developers working on the Twisted source code itself should
  either (1) run all tests under tox, or (2) run 'python setup.py
  develop' to install trial before running any tests. (#8765)
- twisted.protocols.gps, deprecated since Twisted 15.2, has been
  removed. (#8787)

=================================

Features
--------
- SSH key fingerprints can be generated using base64 encoded SHA256
  hashes. (#8701)

Bugfixes
--------
- SSHUserAuthServer does not crash on keyboard interactive
  authentication when running on Python 3 (#8771)
- twisted.conch.insults.insults.ServerProtocol no longer corrupts a
  client's display when attempting to set the cursor position, and
  its ECMA-48 terminal manipulation works on Python 3. (#8803)

Twisted Pair 16.5.0 (2016-10-28)
================================

Features
--------
- twisted.pair has been ported to Python 3 (#8744)

Twisted Web 16.5.0 (2016-10-28)
===============================

Bugfixes
--------
- twisted.web.client.HTTPConnectionPool and anything that uses it,
  like twisted.web.client.Agent, have had their logic for resuming
  transports changed so that transports are resumed after state
  machine transitions are complete, rather than before. This change
  allows the HTTP client infrastructure to work with alternative HTTP
  implementations such as HTTP/2 which may be able to deliver a
  complete response synchronously when producing is resumed. (#8720)
