* nsfont.m (ns_attribute_value): Remove.

    (ns_attribute_fvalue): Incorporate code from ns_attribute_value.
    (ns_has_attribute): Shrink the normal range.
    (ns_findfonts): Don't worry about requested spec in determining
      need for synthItal.
    (ns_get_covering_families): Retain scriptToFamilies.
