This is step one of a hundred fifty on the path to case insensitivity. It brings in the basic case folding mechanism and adds it to the mtimefs, as this is something outside the fileset that touches stuff in the database based on name. No effort to convert or handle existing entries when the insensitivity is changed, I don't think we need it... Useless by itself but includes tests and will reduce the review load along the way.
