kvm: Introduce kvm logging interface (Glauber Costa)
Introduce functions to control logging of memory regions.
We select regions based on its start address, a
guest_physical_addr (target_phys_addr_t, in qemu nomenclature).
The main user of this interface right now is VGA optimization
(a way of reducing the number of mmio exits).
