Move rng.{cpp,h} from core to rng/ topdir

Add a new class AutoSeeded_RNG that is a RandomNumberGenerator that wraps
up the logic formerly in RandomNumberGenerator::make_rng. make_rng in
fact now just returns a new AutoSeeded_RNG object.

AutoSeeded_RNG is a bit more convenient because

- No need to use auto_ptr
- No need to dereference (same syntax everywhere - it's an underestimated
advantage imo)

Also move the code from timer/timer_base to timer/
