It neglected to update existing code, which continues to use int64_t. migrate_xbzrle_cache_size() returns the new parameter. Adjust its return type. QMP query-migrate-cache-size returns migrate_xbzrle_cache_size(). Adjust its return type. migrate-set-parameters passes the new parameter to xbzrle_cache_resize(). Adjust its parameter type. xbzrle_cache_resize() passes it on to cache_init(). Adjust its parameter type.
