-------------------------------+------------------------
 #2818 changed the "Connected Servers" table on the welcome page, to make
 the "Address" column show the full connection hint list, instead of the
 one address returned by `rref.getPeer()`. This makes e.g. Tor connections
 over unix-domain SOCKS sockets nicer, but makes plain TCP hints
 (especially when the target advertises multiple connection hints) more
 verbose.

 [Foolscap#267 https://foolscap.lothar.com/trac/ticket/267] is about adding
 a new !RemoteReference API that could give us nicer information.
 Specifically, it would tell us *how* the connection was made (which
 handler, which hint, maybe which IP address the hostname resolved to),
 rather than just the intended target of the FURL. That could provide some
 assurance that we really did use Tor, for example.

 So this ticket is about adding `IServer.get_connection_info()` to
 !NativeStorageServer, which delegates to the new Foolscap API, and then
 changing `allmydata.web.root.Root.render_service_row()` to use the new
 information instead of `server.get_remote_host()` (which could probably be
 removed altogether).

 I'm tenatively scheduling this for the 1.12 milestone, because the default
 tub.location=AUTO yields hints for every interface, which makes this
 Welcome-page display pretty ugly, and I'd like to see that fixed. But it
 depends upon the new Foolscap API, which I haven't finished specing out
 yet, so I stand prepared to drop this from 1.12 if that doesn't happen
 soon.
