xen: use our own eventchannel->irq path
Rather than overloading vectors for event channels, take full responsibility for mapping an event channel to irq directly. With this patch Xen has its own irq allocator. When the kernel gets an event channel upcall, it maps the event channel number to an irq and injects it into the normal interrupt path.
