In this revision, I'm now trying the approach of backend/frontend
split-ups for the affected IRQ chips. That means we keep a single qdev
device description but fork off specific logic early during device init.
The backends support this by providing hooks that user space and KVM
models can implement differently.
The result is slightly larger and comes with the not really beautiful
ioapic.kvm_gsi_base property but should otherwise meet expectations.
Comments?
PS: Series is still against old uq/master, therefore containing patches
that took/will take different routes.
