This belongs where the PIT is created and allows us to drop another
kvm_irqchip reference.

Upstream is moving towards this mechanism, so start using it in qemu-kvm
already to configure the specific defaults: kvm enabled on, just like
in-kernel irqchips.

Replace qemu-kvm's versions of kvm_add_irq_route, kvm_add_routing_entry,
kvm_init_irq_routing, kvm_arch_init_irq_routing, and
kvm_commit_irq_routes with the corresponding upstream services. Until
the MSI API is refactored, we only need to export kvm_add_routing_entry
for this.

Drop the qemu-kvm version in favor of the equivalent upstream
implementation. This allows to move the i8259 back into the hwlib.
Note that this also drops the testdev hack and restores proper
isa_get_irq. If testdev scripts exist that inject > IRQ15, they need
fixing. Testing for these interrupts on the PIIX3 makes no practical
sense anyway as those lines are unused.
