This removes quite a bit of code. All reasonable systems have /dev/urandom these days. Linux, Solaris and the BSDs do. In case we find a system without /dev/urandom, we will have to go hunting in other libraries. The main reason for this is speed: On Ubuntu 14.04 doing direct reads from /dev/urandom is 2-3 times faster than our md4 based code. On virtualized FreeBSD 10 the difference is even larger. My first approach was to use fopen/fread. It was even faster, but less than twice as fast. So I thought we could save the additional complexity when having to deal with throwing away buffers when forking and the additional memory footprint per process. With this simple generate_random_buffer it will be easier to adapt new syscalls to get randomness.
