Replace the rand() which reads from /dev/random with a Mersenne PRNG.
...
Much better now.
Also, it is seeded by reading from /dev/random at startup. Not sure if that's the best idea, but we'll see.

libc: Implement atexit() and _exit()

And initialize_libc() can now register a handler to close stdout and stderr on program termination!! :)

what were before one extern FILE* without reference now are opened by libc on program initialization, to point to /dev/console by default.
