Use of these macros, apart from the benefits mentioned in the commit that adds the macros, has some other good side effects: - Consistency in getting the size of the object from sizeof(type), instead of a mix of sizeof(type) sometimes and sizeof(*p) other times. - More readable code: no casts, and no sizeof(), so also shorter lines that we don't need to cut. - Consistency in using array allocation calls for allocations of arrays of objects, even when the object size is 1.
