Add DB storage for enabling / disabling arbitrary RAT types.
Parse new GSUP IE indicating the RAT types employed by the subscriber.
Store allowed RAT types in the database.
Reject LU if used RAT type is not allowed.
So far we have only GERAN-A and UTRAN-Iu, but to be future compatible,
implement an arbitrary length list of RAT types: add DB table subscriber_rat.
Backwards compatibility: if there is no entry in subscriber_rat, all RAT types
shall be allowed. As soon as there is an entry, it can either be false to
forbid a RAT or true to still allow a RAT type.
