Add weak platform independent PRNG to test framework.
Implement the GNU C library's random(3) pseudorandom number generator.
The algorithm is described: https://www.mscs.dal.ca/~selinger/random/
The rationale is to make the tests repeatable across differing platforms with
different underlying implementations of the random(3) library call.
More specifically: when executing tests with random ordering.
[extended tests]
