Use the same implementation for the PatchLineComment and CommentInfo versions, which takes into account more fields. Some differences arose because they were used in different places under different assumptions about which fields would vary. Since these are now used in a variety of places, be more general. Move both to the same location, so it's easier to see side-by-side that the implementation matches. Use Ordering so callers can use convenience methods where convenient.
