Statically to start with. The dynamic case implies a
system which has an allocator, and lwip assumes nothing.

It's really a not-so-big change, but it helps implementing
new protocols in a clean way. And it might facilitate
the dynamic adding, removal or restarting of (app layer)
protocols, which isn't possible now.

That's the reason why I started the discussion.

This makes sense if lwip or parts of it are used
for a limited timespan.

I'll try to make it flexible enough to accomodate
future extensions and keep it simple at the same time.

And I'll just create a patch, to avoid a discussion
on tiny details. We'll address them later...
