* Implement (derive) `Clone` for `ChaChaRng`, `Isaac*Rng`, `StdRng` and `ThreadRng`; * Derive `XorShiftRng` `Clone` implementation instead of implementing it explicitly. `OsRng` is the only Rng which does not implement `Clone` or `Copy` after this patch because of its dependence on `Reader`. r? @huonw I guess?
