* randomUUID now creates the RNG only once per thread.
* randomUUID lazily seeds the RNG once (per thread) on the first
  function call
* randomUUID now uses the new seed overload (requires
  https://github.com/D-Programming-Language/phobos/pull/627 )
* the unsafe randomUUID overload taking only a type has been removed.
