It was pretty ill-defined before and mostly for logging. But I wanted
to start depending on it, so define what it is and make Windows match
the other operating systems, without losing the log output we had
before. (and add tests for that)

It wasn't using the right metric. Apparently you're supposed to sum the route
metric and interface metric. Whoops.
While here, optimize a few little things too, not that this code
should be too hot.
Fixes#2707 (at least; probably dups but I'm failing to find)

Not used for anything yet (except logging), but populate the current
proxy autoconfig PAC URL in Interfaces.State.
A future change will do things based on it.
Also remove rebinding logic from the windows router. Magicsock will
instead rebind based on link change signals.
