std::rand: add distributions::Range for generating [lo, hi).
This reifies the computations required for uniformity done by (the old) `Rng.gen_integer_range` (now Rng.gen_range), so that they can be amortised over many invocations, if it is called in a loop. Also, it makes it correct, but using a trait + impls for each type, rather than trying to coerce `Int` + `u64` to do the right thing. This also makes it more extensible, e.g. big integers could & should implement SampleRange.
