libc: Add very basic strtoul()
...
As well as returning NULL in getenv() instead of aborting.

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.

Add VERY HACKY rand() implementation.

libc: Implement atoi(), atol() and atoll()

libc: Implement _Exit
...
Exactly the same as _exit, but in stdlib.h instead of unistd.h

libc: Make functions with no arguments be defined as type function(void)
...
Instead of type function().

libc: Change bits/macros.h to use a __lc_ prefix for internal macros
...
That way, we don't pollute user programs with our own 'noreturn' and 'deprecated' macros

libc: Implement atexit() and _exit()
...
exit() now calls registered handlers before calling _exit().
And initialize_libc() can now register a handler to close stdout and stderr on program termination!! :)

libc: Document functions in stdlib.h
...
Also, add prototypes for calloc() and realloc(), which were already implemented but not in the header.

libc: Rename the _ folder to bits, as used internally by libraries
