Kernel: Acquire ISA interrupt overrides from Interrupt Management

Browse source 
Also, InterruptDisabler were added to prevent critical function from
being interrupted. In addition, the interrupt numbers are abstracted
from IDT offsets, thus, allowing to create a better routing scheme
when using IOAPICs for interrupt redirection.
