Split telephony into its own product, so that we can easily
add telephony support to any configuration without pulling
anything else. Use it from generic.
Split the "full" family between a (no-telephony) base,
a telephony version of the same (both of which can be used
as a starting point for on-device builds), and the true classic
full which is an emulator build.
