Since we are adding a new "per-hypervisor" protocol, we make it so that the qemu remote protocol uses a new PROTOCOL and PROGRAM number. This allows us to easily distinguish it from the normal REMOTE protocol. This necessitates changing the proc in remote_message_header from a "remote_procedure" to an "unsigned", which should be the same size (and thus preserve the on-wire protocol). Changes since v1: - Fixed up a couple of script problems in remote_generate_stubs.pl - Switch an int flag to a bool in dispatch.c Changes since v2: - None Changes since v3: - Change unsigned proc to signed proc, to conform to spec Signed-off-by: Chris Lalancette <clalance@redhat.com>
