Modified Files:
        src/sys/kern: kern_rndpool.c

Log Message:
Correct use of entropy estimate when data are extracted from the pool.

The "threshold" value was being inappropriately used to limit how many
bytes could be output even after the estimator said enough bytes had
been put in to meet our minimum security guarantee.

This fixes a panic observed with the automatic test harness and by
msaitoh, where it was not possible to extract the full estimate's worth
of bytes even holding the pool lock across the estimate and extract
calls.
