Luigi Toscano cdbc98572d More compatibility with Python 3
- use the six version of configparser and urllib, and depends on six;
- remove relative imports;
- adapt few tests to the changes.

The changes above should be noop from the point of view of
functionalities, at least on python 2.

And also:
- replace the py34 tox virtualenv with py35;
- add a non-voting py35 job (locally for now, it will be enabled
  to project-config also for gating when stable).
