Yeah. The date notwithstanding, I do actually think we should do most
of this for real.

Maybe we don't get away with the actual deprecation and the warnings on
use *just* yet, and *maybe* we won't even get away with calling the
config option CONFIG_LEGACY_IP, although I would genuinely like to see
us moving consistently towards saying "Legacy IP" instead of "IPv4"
everywhere.

But we *should* clean up the separation of CONFIG_INET and
CONFIG_IPV[64] and make it possible to build with either protocol
alone.
