The six way of doing this is to replace all occurences of "unicode"
with "six.text_type". However, "unicode" is non-ambiguous and
(arguably) easier to read. Also, using it makes the patches smaller,
which should help with backporting.

Rename __unicode__ to __str__ in classes which define it and use the
six.python_2_unicode_compatible decorator on them to make them compatible with
both Python 2 and 3.
Additional changes were required for the ipapython.dnsutil.DNSName class,
because it defined both __str__ and __unicode__.
