Previously callbacks would return a list of flags, such as [] or [`Created_files]. In this commit we introduce two new objects, filesystem_side_effects and device_side_effects (the latter is not used yet). The callbacks that create files now need to call side_effects#created_file () instead of returning flags. There is no functional change in this patch.
