New switch always resolves names

Created by: stephanemagnenat

The new switch (summer 2016 re-factoring of http2 into switch) always resolve names, while the original one would not if both verbose and dump are omitted. As targets are exposed through HTTP, this resolution makes sense, but in some cases it might be a problem on embedded platforms with wrongly-configured name resolutions. Yet I think that this feature regression is acceptable as named resolution should be properly configured in the first place.
