Support ram slot configuration in libvhost-user
The VHOST_USER_GET_MAX_MEM_SLOTS message allows a vhost-user backend to
specify a maximum number of ram slots it is willing to support. This
change adds support for libvhost-user to process this message. For now
the backend will reply with 8 as the maximum number of regions
supported.
libvhost-user does not yet support the vhost-user protocol feature
VHOST_USER_PROTOCOL_F_CONFIGIRE_MEM_SLOTS, so qemu should never
send the VHOST_USER_GET_MAX_MEM_SLOTS message. Therefore this new
functionality is not currently used.
