Kernel: rewrite the whole kmalloc (again)
...
Performance of the old kmalloc implementation was terrible.
We now use fixed-width linked list allocations for sizes <= 60 bytes.
This is much faster than variable size allocation.
We don't use bitmap scanning anymore since it was probably the slow
part. Instead we use headers that tell allocations size and aligment.
I removed the kmalloc_eternal, even though it was very fast, there is
not really any need for it, since the only place it was used in was IDT.
These changes allowed my psf (font) parsing to go from ~500 ms to ~20 ms.
(coming soon :D)

*Applies to last patch also!*
Remove duplicate code in iterators. We used to have separate iterator
and const_iterator but now they are the same class with some enable_if
magic to disable references from const_iterator
This introduces some 'bad things' you can for example call
const_iterator.operator*<false>() to obtain non const reference. I
don't think this matters since you could use const_cast or something
else to work around const if you really tried

We don't use grub-mkrescue anymore. Instead we build the disk image

implement.
