marcel 87a4ad12f0 Don't send EOI to the CPU before we handled the interrupt. This could
potentially trigger multiple pending interrupts for level-sensitive
interrupts.  However, the event timer interrupt does need EOI before
being handled to avoid missing clock events.

These conflicting requirements are handled by having the XIV handler
inform the dispatch code whether or not it send EOI to the CPU. If not,
the dispatch code will do it. This allows handlers to send EOI before
doing potentially long-running activities, while still have a sensible
default behaviour.
