f0093ed2fd Kernel: kmalloc_eternal now updates the used/free values 
I also improved the kmalloc_dump_info() formatting. We format the
values as 8-digit hex numbers since (atleast for now) the kmalloc
will always be under 4 GiB address and size :)

e87026f01d Kernel: I have no idea what this commit does 
I had committed a change in IDT but reverted it now.

This propably only adds a spurious interrupt detection to common cpp
interrupt handler?

c0bc002ac6 Kernel: Move debug printing to its own file 
It didn't make sense that dprint was defined in Serial.h.
We also now dump dprint to tty if there is no serial and tty is initialized

54043288cb Kernel: Move CPUID out of arch/ 
CPUID instructions behaves the same on x86 and x86_64. I am not
planning on supporting any non x86 based architectures.

1b9f7aa815 Kernel: Rewrite the whole VESA driver 
We dont support vga text mode currently. I might add it later if needed.

I also removed mouse 'support' from Shell since it didn't do anything
and I didn't implement arbitary bitmap rendering to framebuffer
