This provides the primitive API, as well as exposing it from BABE.

This includes both code to expose them from `srml_system`, as well as
using it in (currently dead) code in `srml_babe`.

needs constants from it.  This adds our own definitions of those
constants, and checks them for correctness at compile-time.
