Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks. Signed-off-by: Avi Kivity <avi@redhat.com>
