This is a big commit that was kinda hard to split to smaller ones.
Essentially we now look at all the mass storage devices from PCI
and initialize (P)ATA devices. This doesn't provide any more functionality
but better abstractions and everything doesn't have to be on its old
default port that might be different for modern computers.

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)
