* shared/irq/irq_supp.h: Make sure BSP_SHARED_HANDLER_SUPPORT
is set. The shared irq manager supports shared interrupts
(but requires also that the PIC-driver supports them by
traversing the list of shared handlers).
Declare C_dispatch_irq_handler() which must be defined
(like the other routines declared in this header) by the
PIC-driver.
