Log Message:
Entropy estimation changes:
1) Avoid wraparound problems with delta estimator by making estimation
framework 64-bit.
2) Adjust rnd_counter to always return a 64-bit value, accordingly.
3) Make delta estimator generic and create two instances: delta-time and
delta-value.
4) Add LZF estimator -- used mostly to protect us against injection of
bulk data we think is random but is really constant.
5) Allow value and time estimation/collection to be controlled separately.
6) Expose estimator performance to userspace.
