Abstraction for hardware based interrupt routine

On non IA-32 systems it is common to have a single hardware interrupt vector and a 2nd layer of software that routes the interrupt handlers based on the interrupt source. This protocol enables this routing. The driver implementing this protocol is responsible for clearing the pending interrupt in the interrupt routing hardware. The HARDWARE_INTERRUPT_HANDLER is responsible for clearing interrupt sources from individual devices.
