A set of vhost-vdpa specific ops callbacks are attached to the virtio_user according to the runtime dynamic check result of the backend type. DMA memory map/unmap callbacks are added to both vdev bus driver and virtio_user pmd to support address mapping. In addition, minor fixes to existing virtio control path are also implemented to make the new backend work. This is a collaborative work done with Patrick Fu from Intel and Adrian Moreno from Red Hat. Thanks to them for their contributions. The series has been tested with vdpasim and Intel IFC Kernel vDPA drivers, and more lightly with Mellanox mlx5_vdpa on ConnectX-6 Dx.
