Test of uniformity of BN_rand_range output.
Rework the test so that it fails far less often.
A number of independent tests are executed and 5% are expected to fail.
The number of such failures follows a binomial distribution which permits
a statistical test a 0.01% expected failure rate.
There is a command line option to enable the stochastic range checking.
It is off by default.
