Support adding individual regions in libvhost-user
When the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS is enabled, qemu will transmit memory regions to a backend individually using the new message VHOST_USER_ADD_MEM_REG. With this change vhost-user backends built with libvhost-user can now map in new memory regions when VHOST_USER_ADD_MEM_REG messages are received. Qemu only sends VHOST_USER_ADD_MEM_REG messages when the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS feature is negotiated, and since it is not yet supported in libvhost-user, this new functionality is not yet used.
