* Clean up random number generator code Depending on the platform, we use a mix of random, rand, and rand_r to generate pseudo-random numbers, along with a messy set of ifdefs in H5private.h. We are not a cryptographic library, only use random numbers in our test code, and have no need for anything more than the C standard's (s)rand(). There's no point dithering about using rand() vs random() when we're also doing bad things like using mod to restrict the range, which introduces bias. Also removes CMake/configure checks for rand_r and random * Remove random/rand_r checks from build system * Fix missed HDrandom after GitHub merge
