        src/sys/kern: kern_entropy.c
        src/sys/sys: entropy.h

Log Message:
entropy(9): Factor out subroutines to reset and gather entropy.

`Reset' means we keep the data in the pool, but assume it had zero
entropy.  `Gather' means we request samples from all on-demand
sources and wait for the synchronous ones to complete.

No functional change intended, other than to expose new symbols --
just preparation to expose these to acpivmgenid(4), so it can use
these when the VM host notifies us that we, the guest, have been
cloned.
