    Rely on /dev/urandom
    
    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.
