Nope, external project sign up themselves for pain if they rely on
internal libraries of samba.

lib/util was never marked a public API and it is not in shape to be
marked as such.

Anyone using it will and *should* get what they paid for (pain) by using
it.
We of course do not want to gratuitously break people, but it is not on
our shoulders to shild others from their risky behavior.

CTDB is not external anymore, for that the bug is that autobuild doesn't
build it standalone, let's fix that.

Simo.
