report res_query failures, including nxdomain/nodata, via h_errno
while it's not clearly documented anywhere, this is the historical behavior which some applications expect. applications which need to see the response packet in these cases, for example to distinguish between nonexistence in a secure vs insecure zone, must already use res_mkquery with res_send in order to be portable, since most if not all other implementations of res_query don't provide it.
