Following feedback and discussion on this draft I've updated it to use a
META RR rather than an EDNS option.

This simplifies questions about adding an OPT RR if one wasn't already
in the proxied packet.  It also avoids (some) issues with TSIG / SIG(0).

This RR now contains the entire 5-tuple of src/dest address and port
(and protocol) and not just the source IP address - the rationale for
this is explained in the draft.

As I won't be present for DNSOP in Prague this is due to be presented by
Peter van Dijk, one of my two new co-authors.

Abstract:
   It is becoming more commonplace to install front end proxy devices in
   front of DNS servers to provide (for example) load balancing or to
   perform transport layer conversions.

   This document defines a meta resource record that allows a DNS server
   to receive information about the client's original transport protocol
   parameters when supplied by trusted proxies.
