From: "Edgar E. Iglesias" <edgar.iglesias@amd.com>

This follows up on the virtio-pci discussion and adds a per-domain
option to select the behaviour of accesses to unmapped address ranges.
The new option is trap_unmapped_accesses, it's general but for now
only implemented for ARM.

I'm happy with any name, so if you have better ideas please suggest them!

I've included regenerated golang bindings as a separate patch.

Thanks,
Edgar
