tsweb: rename Handler to ReturnHandler
...
The name's been bugging me for a long time.
I liked neither the overlap between tsweb.Handler and http.Handler,
nor the name "ServeHTTPErr" which sounds like it's an error being
returned, like it's an error handler and not sometimes a happy path.

tsweb: don't panic if we get a tsweb.Error with no embedded error.
...
It's technically weird to return a tsweb.Error with no child err,
but it's a sensible thing to want to do, and we shouldn't panic
if it happens.

tsweb: use a ResponseWriter wrapper to log more accurately.

Also adds tests, because the logging handler is acquiring a fair

tsweb: add a Handler type.
...
Handler is like http.Handler, but returns errors. ErrHandler
converts back to an http.Handler, with added error handling
and logging.

wgengine/monitor: don't call LinkChange when interfaces look unchanged
...
Basically, don't trust the OS-level link monitor to only tell you
interesting things. Sanity check it.
Also, move the interfaces package into the net directory now that we
have it.
