vpnc-script-win.js seems to wait until the Legacy IP address of the
interface appears in 'route print' output. How that'll work in the
21st century when there's only IPv6 and no Legacy IP, I have no
idea. But set it for now like the old TAP driver did, and see if
we can make it work...

Passes packets. Configuration isn't working properly.
There's lots of memcpy here as Wintun *really* wants us to use its pool.
More thought required for that one, as it can't even handle stripping
packet headers so even if we decrypt directly into its buffer that
wouldn't be enough.
