py3: hack around inconsistency of type of name passed to DNSQuestion I don't like this patch but this is the easiest way I could fix it. There are some callers which pass name which is bytes, some pass name which is str. I just encode() that if that's str. This does makes test-paths.t pass, but I am not confident whether the whole of zeroconf will work on py3 or not. Differential Revision: https://phab.mercurial-scm.org/D6511
