Robert Greenwalt 77b32ddbbe Make the DUN apn data secure.
Rather than come out of the user-modifiable APN DB, the DUN APN data will
come first from a built-in resource and then potentially overriden by a secure
setting (which is gservices upgradable).

Also made the "require-dun" setting secure-setting overridable.
