Re: [PATCH] Make URN support an optional component

Looks quite nice I think.

And while I agree with Adrian that perhaps we should try to not do
additional refactoring and API changes in Squid-3.0 I do not think this
kind of things should be sitting in a private branch. If it's finished
and looking good but not a candidate for 3.0 then it's a good reason for
forking Squid-3.0.

Now this change wasn't that intrusive. Mostly reshuffling to better
isolate things so I don't object having it in 3.0.
