Victor Stinner 6e70f3fa32 Get StringIO and cStringIO from six.moves 
* replace "from cStringIO import StringIO"
  with "from six.moves import cStringIO as StringIO"
* replace "from StringIO import StringIO"
  with "from six import StringIO"
* replace "import cStringIO" and "cStringIO.StringIO()"
  with "from six import moves" and "moves.cStringIO()"
* replace "import StringIO" and "StringIO.StringIO()"
  with "import six" and "six.StringIO()"
