vm-virtio: Add PCI transport support Copied from crosvm 107edb3e with one main modification: VirtioPciDevice implements BusDevice. We need this modification because it is the only way for us to be able to add a VirtioPciDevice to the MMIO bus. Bus insertion takes a BusDevice. The fact that VirtioPciDevice implements PciDevice which itself implements BusDevice does not mean that Rust will automatically downcast a VirtioPciDevice into a BusDevice. crosvm works around that issue by having the PCI, virtio and BusDevice implementations in the same crate.

vm-virtio: Add MMIO transport Derived from the crosvm code at 5656c124af2bb956dba19e409a269ca588c685e3 and adapted to work within cloud-hypervisor: Main differences: * Interrupt handling is done via a VirtioInterrupt turned into a devices::Interrupt * GuestMemory -> GuestMemoryMmap * Differences in read/write for BusDevice * Different crates for EventFd and GuestAddress Signed-off-by: Rob Bradford <robert.bradford@intel.com>
