Bug#712513: python-debian: PkgRelation.parse_relations() prints warning on stderr

[Jakub Wilk]

Source: python-debian
Version: 0.1.21+nmu2

PkgRelation.parse_relations() does this:

                 print('deb822.py: WARNING: cannot parse package' \
                       ' relationship "%s", returning it raw' % raw,
                       file=sys.stderr)

Please use the warnings[0] mechanism instead, so that applications can 
easily suppress the warning, or turn it into an exception if they wish 
so.
