Rewrite DNS API from scratch into dedicated file(s)
From a functional point of view, the main improvement is that GetIP() now always prioritizes IPv6 over IPv4. The previous implementation always returned an IPv4 address, unless not available: in such case it failed. This means that now connections to hostnames should be established via IPv6 if available. From a programmer point of view, getting rid of the insane wrappers is enough to justify a complete rewrite. As an extra, several unrelated unused global variables are removed.
