Code review comment for lp:~widelands-dev/widelands/net-boost-asio

* Hmm, here is the IPv6 Error:
[LAN] Started an IPv6 socket on UDP port 7394.
...
[LAN] Will broadcast for IPv6.
[LAN] Error when broadcasting on IPv6 socket, closing it: No route to host.
[LAN] Closing an IPv6 socket.

Must use debugger/consult docs what this is about.
Looks Broadcast adresses in IPv6 need some differetn aproach.

* Testing lcoal network (OSX)
  server <- client
  asio <- asio game is not visible in the local network browser (but is fast)
            but can connect via localhost
  old <- asio game is visible in the local network browser (but slow setting this up)
            connection works as expected
  asio <- old game is visible in the local network browser
            connection works as expected

Now I am puzzeld an will need some debugging to find this.
(And we will need some Linux, OSX, Windows ... LAN Party for the final checks :-)

Notabilis please give some hint where to check.

As its is bsiaclly working I would like to see some > 30 min Internet game,
for stabilit, we then vould write seom bugs for our findings.

I will start the code review now, while wating for some victim in the lobby for testing :-)
