[upuplxco] Much faster than urandom

A program which writes random data to stdout, but is not cryptographically secure like /dev/urandom.

Perhaps useful for overwriting a disk which formerly contained sensitive data.

We again use an inlineable version of the GNU libc random number generator, but initialize it with random data instead of a linear congruential.

800 times faster than urandom, for writing to /dev/null
