Accepting "0.0.0.0" is a hack, not a "standard behaviour" for UNIX-like
OSes. I know that NetBSD has become less accepting of 0.0.0.0 as an
"all addresses" alias.

Is ListenAddress 0.0.0.0 a no-op? It looks like it is, but I don't have
a multi-interface machine on which I can check. If it's not, then maybe
we need to make people specify all ListenAddress'es or maybe we need to
let the default be to listen on all addresses unless a ListenAddress is
specified, and then it won't listen to any other source address.
