Type changes
Only allow properties inside objects, this makes it easier to iterate the object, which is needed for efficiently processing control streams. Add a choice type to mark variable properties. SPA_TYPE_Enum -> SPA_TYPE_Id to avoid confusion with choice enum Make it easier to allocate and initialize properties on the stack Make more efficient methods to make objects.
