        Minor tweaks:
                Cleaned up the code a little and added some pre-1.3.0 tweaks.
                dev->hard_header/hard_header_len changed to use no headers.
                Comments/bracketing tweaked.
                Made the tunnels use dev->name not tunnel: when error reporting.
