In Squid-3.1+ the above info should all be stored in fde via Ip::Address.
Which holds the port paired with address, unless erased by some update.
Failing that the ConnectionDetails objects store it all (not available in
most of the code though). I'm currently working on comm upgrades to make
this info easily passed around, they are deadlined for "any time now".
