Stage www/squid33

This port needed a *lot* of love, and it needs a lot more. It has a
ton of options (Do we need so many options rather than enabled by
default?) and I suspect many options aren't staged properly. Also the
way the plist is put together is crazy. This needs a proper static
pkg-plist with PLIST_SUB switches. This port badly needs a full-time
maintainer. (www/squid32 and www/squid are just as bad)

I also added patch from PR 192119 while I was here.
