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: Move errno.h and (k)assert.h out of the main include directory

This is mostly so IDEs don't pick them up instead of the userspace headers :)

VFS: Implement resolve_path and form the initial ramdisk's VFS properly
...
Finally, resolve_path: a function which takes a path (/etc/fstab for example), and walks the VFS:
In this case, it would start with the root FS node, and ask it: "do you have a directory/file named etc?"
The node could say 'yes', 'no', or 'i'm not a directory, I'm a file' (should not be the case for the VFS root, but for the other ones it could be)
If it says yes, we continue and ask the child if it has a file named fstab. Etc...
