Generic PRNG framework:

Browse Source 
* A new, unified interface for generating random numbers and
  filling buffers supporting any engine that fits the
  UniformRandomNumberGenerator concept;
* Automatically seeded replacement for rand using the fast
  xorshift+ PRNG engine;
* A CSPRNG engine that can be used with the new framework
  when needing to to generate cryptographically secure
  randomness.
* Unit test cleanups to work with new engine.
