26974c7625 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

c042483953 build: make PCI (virtio and vfio) disableable at build time
Although included by default it is now possible to build without PCI
support.

c2c51dc9d1 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.
