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

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

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

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.

Kernel, libc: Add support for providing a status code to exit()
...
The exit() libc function already accepted an integer, but didn't pass it on to the kernel since we had no mechanism for it to do that.
Now, the kernel stores a task's exit status to display it later (and in the future, return it to userspace via wait()/waitpid())

Add mmap and munmap syscalls, and thus, add malloc and free to libc!! (yet again, thanks to the wonderful liballoc)
