vector stubs and into the C functions they call. - Move disabling and EOIing of interrupt sources out of PIC driver entry points and into intr_execute_handlers(). Intr_execute_handlers() only disables a source for an interrupt if it is a stray interrupt or has threaded handlers. Sources with fast handlers no longer disable (mask) the source while executing the handlers. - Move the setting of clkintr_pending into intr_execute_handlers() and set the variable for any interrupt source with a vector of 0. (Should only be true for IRQ 0.) This fixes clkintr_pending in the NO_MIXED_MODE case. - Implement lapic_eoi() and use it to implement ioapic_eoi_source(). - Rename atpic_sched_ithd() to atpic_handle_intr() since it is used to handle all atpic interrupts and not just threaded ones.
