Kernel: Add a heap memory allocator
...
This is the first time I've actually dropped liballoc in favor of writing my own implementation.
Usually, malloc() and such looked so complicated that I preferred to let a nice external library do the job.
But I've decided to try writing my own allocator, and now we have heap memory without any 3rd party code!

Kernel: Use framebuffer virtual address instead of physical address
...
Just found out bootboot.fb_ptr was the physical address, not virtual.
That explains why we were getting page faults while writing to the physical address of the framebuffer. (we were in a user address space when doing so)
So this should probably make the system much more stable!!

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.

This page-faults. This is because the memory where the ELF should be is all zeroes, which the CPU tries to interpret.
