 * include settings that are safe to change.
 *
 * @todo: Only the field type module knows which settings will affect the
 * field's schema, but only the field storage module knows what schema
 * changes are permitted once a field already has data. Probably we need an
 * easy way for a field type module to ask whether an update to a new schema
 * will be allowed without having to build up a fake $prior_field structure
