KVM: In-kernel I/O APIC model
This allows in-kernel host-side device drivers to raise guest interrupts
without going to userspace.
[avi: fix level-triggered interrupt redelivery on eoi]
[avi: add missing #include]
[avi: avoid redelivery of edge-triggered interrupt]
[avi: implement polarity]
[avi: don't deliver edge-triggered interrupts when unmasking]
[avi: fix host oops on invalid guest access]
