The changes in this file cover the enum message requests for supporting add/remove memory regions. The front-end vhost-user client sends messages like get max memory slots, add memory region and remove memory region which are covered in these changes which are on the vhost-user back-end. The changes also include data structure definition of memory region to be added/removed. The data structure VhostUserMsg has been changed to include the memory region.
