Note that the new functions have a `name` parameter because the plan is to eventually get rid of the Property.name field. The declarations for the new functions are being added to qdev-properties-internal.h, but they will be moved to a QOM header later. Signed-off-by: Eduardo Habkost --- Changes v2 -> v3: * Re-added array-based array registration function, named as object_class_add_field_properties() * Renamed object_class_property_add_field() to object_class_property_add_field_static(), to indicate that the function expect the Property argument to have static life time. * Keep all new functions as internal API by now, until we decide what's going to be the preferred API for registering class field properties. Changes v1 -> v2: * Patch redone after changes in previous patches in the series * Rename new functions to object*_property_add_field() --- Cc: Paolo Bonzini Cc: "Daniel P.
