FDN has serious implications for the rest of the system, particularly on
SMS atom and Sim Toolkit.  oFono will either have to support the entire
thing properly or use a 'limited' FDN mode (e.g. if FDN is enabled, we
only permit emergency calls.)

We have really not made our mind what makes sense here yet.
