Message:

Introduce PIC operations indirection mechanism

Some architectures switch from one interrupt controller implementation
to another during runtime. By providing a cleaner indirection mechanism,
it is possible e.g. for the ia32 IRQ 7 handler to distinguish i8259
spurious interrupts from actual IRQ 7 device interrupts, even when the
i8259 interrupt controller is no longer active.
