Hi all,

This mainly means that the tcp/udp/raw API uses dual-version IP 
addresses everywhere and most of the IPv6-specific functions/defines are 
removed.

I'm just pushing this now to get forward on 1.5.0, but please feel free 
to share your critics here!

I hope that there are no compiler errors left, but given the amount of 
possible define-combinations and function-like-defines I might not all 
use, chances are I missed some, so please share them here if you find any.

The next step (which I already started with that commit) is task #13480 
(lwIP as IPv6 only stack).
