Ted, Linus: there are two ways we can do this: we can either change the
credit_entropy_bits() interface to take some kind of fractional bits as
interface, or we can change the accounting internally.
The latter has the advantage of being a less invasive change, but the
former has the advantage of making it possible to credit sub-bit entropy.
Do you have a preference? Otherwise I will probably write up the
internal change for now.
