Mathias Hall-Andersen 996c7c4d8a Removed IFF_NO_PI from TUN linux 
This change was needed for the Linux TUN status hack
to work properly (not increment the error counter).

This commit also updates the TUN interface to allow for
the construction / removal of the TUN info headers in-place.

Mathias Hall-Andersen cba1d6585a Number of fixes in response to code review 
This version cannot complete a handshake.
The program will panic upon receiving any message on the UDP socket.
