I think this shouldn't be left on the unbound application developer.
Similarly to ub_ctx_hosts() and ub_ctx_resolvconf() there should be an
option to try some sensible defaults. E.g. try to find the unbound
root.key file, then try the bind one, and so on. Then patches for the
various unsupported systems will come to unbound from developers
working with them. Otherwise this discovery phase will be duplicated
on every project using unbound, and possibly with varying success.

I develop a dane library to be used with gnutls and I cannot really
run external applications. I'll try to do the root.key discovery, and
if not found I'll return an error to the library user.
