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`.

Otherwise, it errors out at compile-time.

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

XOR is not a hash function, and must not be used as such.  The
implementation was also needlessly unsafe.
