Kernel, libc: Implement fork()
...
This time for real.
Also, add a new per-user-task virtual address allocator (UserHeap), so that mmap'ed pages are in user range and can be copied.

Kernel: on stack smashing detection, do not trigger a normal panic

That triggers stack traces, which we do not want in a stack smash fail situation

Kernel, libc: Implement spawn()
...
This function is a Luna alternative to fork() and exec().
Why? Simply because I can't figure out for the life of me how to implement a working fork().
So meanwhile, we have spawn() as a replacement. exec() still exists, though.

Kernel: Switch to strlcpy() as well
...
Surprisingly, most uses of strncpy() are in places where strncpy() is actually a better choice.
For example, copying to a fixed-length char array in a structure.

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.
