    [Python3] Fix python3 bugs in code

    - The BaseException class no longer has a "message"
      attribute in python 3 [1]. On the contrary, the
      string representation of an Exception object will
      print all the exception args in all supported
      python versions, so use that instead.
    - Functional tests were run with a specific locale,
      remove those annotations so we can handle unicode
      encoding and decoding in python3 envs.
    - Cleanup errors were not being handled correctly,
      cleanup the code so we don't have spurious failures.
    - In python3, dict.keys() gives you a view for lazy
      loading, so convert occurrences to lists as expected
      in our functional tests.
    - Start capturing STDOUT and STDERR in tox envs to
      enable troubleshooting.
