    This commit introduces a vhost-user-scsi backend sample application. It
    must be linked with libiscsi and libvhost-user.
    
    To use it, compile with:
      $ make vhost-user-scsi
    
    And run as follows:
      $ ./vhost-user-scsi -u vus.sock -i iscsi://uri_to_target/
      $ qemu-system-x86_64 --enable-kvm -m 512 \
          -object memory-backend-file,id=mem,size=512m,share=on,mem-path=guestmem \
          -numa node,memdev=mem \
          -chardev socket,id=vhost-user-scsi,path=vus.sock \
          -device vhost-user-scsi-pci,chardev=vhost-user-scsi \
    
    The application is currently limited at one LUN only and it processes
    requests synchronously (therefore only achieving QD1). The purpose of
    the code is to show how a backend can be implemented and to test the
    vhost-user-scsi Qemu implementation.
    
    If a different instance of this vhost-user-scsi application is executed
    at a remote host, a VM can be live migrated to such a host.
