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?

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

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.

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
