In my "build everything" tree, changing hw/irq.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). hw/hw.h supposedly includes it for convenience. Several other headers include it just to get qemu_irq and.or qemu_irq_handler. Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to qemu/typedefs.h, and then include hw/irq.h only where it's still needed. Touching it now recompiles only some 500 objects.
