[PATCH 2/2] Add -mem-shared option

Add an option to simplify shared memory / vhost-user setup. Currently, using vhost-user requires NUMA setup such as: -m 4G -object memory-backend-file,id=mem,size=4G,mem-path=/dev/shm,share=on -numa node,memdev=mem As there is no other way to allocate shareable RAM, afaik. -mem-shared aims to h
