Historically, sending all memory regions to vhost-user backends in a single message imposed a limitation on the number of times memory could be hot-added to a VM with a vhost-user device. Now that backends which support the VHOST_USER_PROTOCOL_F_CONFIGURE_SLOTS send memory regions individually, we no longer need to impose this limitation on devices which support this feature. With this change, VMs with a vhost-user device which supports the VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS can support a configurable number of memory slots, up to the maximum allowed by the target platform. Existing backends which do not support VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS are unaffected.
