PCI device assignment to guests
The main change from the patches I sent out earlier this week is support for guests that use the PIC. A callback for PIC irq ack handling is also introduced.
Currently, there's no mechanism to register/unregister callers to the irq ack callbacks, but they can be added when there's more than one user for the functionality.
Please review.
