* shared/irq/i8259.c, shared/irq/irq.h, shared/irq/irq_supp.h,
shared/irq/openpic_i8259_irq.c: BSP_disable_irq_at_pic(),
openpic_disable_irq(), BSP_irq_disable_at_i8259s() now return
0/1 if irq was disabled/enabled prior to disabling.
irq_supp.h now exports a inline helper routine for scanning
a list of shared handlers; to be used by PIC drivers.
