Buildsystem: Build disk image manually
...
We don't use grub-mkrescue anymore. Instead we build the disk image
manually. This allows us to have known disk layout for easier testing
when I get to implementing disk reading. For now I made the root
partition ext2 since I think that will be the first format that I'll
implement.

I also implemented multithreading for i386 since it was not done

Kernel: Implement somewhat functioning multithread support

This still uses only a single cpu, but we can now have 'parallelization'
This seems to work fine in qemu and bochs, but my own computer did not
like this when I last tried.
I have absolutely no idea how multithreading should actually be
implmemented and I just thought and implemented the most simple one I
could think of. This might not be in any way correct :D
