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.

 2017-07-15 16:27:59 +02:00
Mathias Hall-Andersen b21c82e32d Conforming to the cross-platform UX 
The implementation now terminates when the unix socket is deleted.
Currently we are unable to use fsnotify (on linux),
since it does not notify on the deletion of open files.

The implementation can now daemonize (on linux)
or be kept in the foreground by providing the necessary flag.

Mathias Hall-Andersen 8993b3927c Improved throughput 
- Improved performance by adding the message buffers to a sync.Pool.
- Fixed issue with computing "next" key-pair upon
  receiving a response message.

Mathias Hall-Andersen 1868d15914 Beginning work on TUN interface 
And outbound routing

I am not entirely convinced the use of net.IP is a good idea,
since the internal representation of net.IP is a byte slice
and all constructor functions in "net" return 16 byte slices
(padded for IPv4), while the use in this project uses 4 byte slices.
Which may be confusing.
