Check TXT lookup results on Windows
In the Windows implementation of k5_try_realm_txt_rr(), iterate
through the received records and pick one that is a non-empty TXT
record. Otherwise the function could dereference an invalid pointer
and crash (depending on the behavior of DnsQuery_UTF8(), which is not
fully known). Discovered by Aisle Research.
