Preparation for generating bookmaker files for all remaining interfaces Standardize enum and enum classes by including a comma after the last entry. Replace flatten-related #define in public interfaces with their equivalent. The motivation is to give documentation something to refer to. An alternative would be to move part or all of this out of the public interface; something I can work on in a follow-up CL.

different set of path segments.
