CPR must save state that is needed after QEMU is restarted, when devices are realized. Thus the extra state cannot be saved in the migration channel, as objects must already exist before that channel can be loaded. Instead, define auxilliary state structures and vmstate descriptions, not associated with any registered object, and serialize the aux state to a cpr-specific channel in cpr_state_save. Deserialize in cpr_state_load after QEMU restarts, before devices are realized. Provide accessors for clients to register file descriptors for saving. The mechanism for passing the fd's to the new process will be specific to each migration mode, and added in subsequent patches.
