pytest 2.8.6 released

[Bruno Oliveira]

Hey everyone,

I'm happy to announce pytest 2.8.6 has been released.

pytest is a widely used mature test runner both for unit and functional
tests in Python.
See http://pytest.org for documentation and examples.

Here are the fixes for this release:

- fix #1259: allow for double nodeids in junitxml,
  this was a regression failing plugins combinations
  like pytest-pep8 + pytest-flakes

- Workaround for exception that occurs in pyreadline when using
  ``--pdb`` with standard I/O capture enabled.
  Thanks Erik M. Bray for the PR.

- fix #900: Better error message in case the target of a ``monkeypatch``
call
  raises an ``ImportError``.

- fix #1292: monkeypatch calls (setattr, setenv, etc.) are now O(1).
  Thanks David R. MacIver for the report and Bruno Oliveira for the PR.

- fix #1223: captured stdout and stderr are now properly displayed before
  entering pdb when ``--pdb`` is used instead of being thrown away.
  Thanks Cal Leeming for the PR.

- fix #1305: pytest warnings emitted during ``pytest_terminal_summary`` are
now
  properly displayed.
  Thanks Ionel Maries Cristian for the report and Bruno Oliveira for the PR.

- fix #628: fixed internal UnicodeDecodeError when doctests contain unicode.
  Thanks Jason R. Coombs for the report and Bruno Oliveira for the PR.

- fix #1334: Add captured stdout to jUnit XML report on setup error.
  Thanks Georgy Dyuldin for the PR.
