  Log:
  Catch "loops" in compressed DNS names the same way the BSD DNS resolver,
  and BIND, do, by counting the number of characters we look at and, if
  when we see a pointer, we see we've already looked at as many characters
  as there are in the DNS packet, we conclude that we're looping.
  
  Also, check for pointers that point past the end of the packet (not just
  past the end of the captured portion of the packet, i.e. cases where we
  didn't capture all of the packet, but cases where the packet is actually
  malformed).
