* Expose rawReq.server.endpoint in JS
* Make rawReq.portType enumerable
This is not strictly necessary but we don't gain much from hiding its existence.
* Allow using http: protocol in local requests
This helps distinguishing local request URLs from file paths in ambiguous contexts.
The alternative would require the user to specify the local endpoint but this doesn't work with
sockets (and for non-sockets would incur the penalty of a real network roundtrip).
* Teach Foxx req.makeAbsolute about unix sockets
* Add Foxx socket tests
