That is correct up to a point - the is_host function got moved into
netutils - there are a number of plugins that wrap system calls that do
network connections. All these now need netutils.h, even though the do
not link to netutils.o.

Personanly, I find this to be a confusing state of affairs and I'd
prefer that is_host be in utils if it could.
