Extend the order module to provide simple, standard, comparison
callbacks for scalar types (i.e. integer and floating point types).
In addition to the usual variants comparing a plain scalar, this also
provides helper macros to construct a suitably typed callback and context
pointer to order structures by a specified scalar field.
