vduse-blk: Implement vduse-blk export
This implements a VDUSE block backends based on the libvduse library. We can use it to export the BDSs for both VM and container (host) usage. The new command-line syntax is: $ qemu-storage-daemon \ --blockdev file,node-name=drive0,filename=test.img \ --export vduse-blk,node-name=drive0,id=vduse-export0,writable=on After the qemu-storage-daemon started, we need to use the "vdpa" command to attach the device to vDPA bus: $ vdpa dev add name vduse-export0 mgmtdev vduse Also the device must be removed via the "vdpa" command before we stop the qemu-storage-daemon.
