Distinguish the case of no directive present (D_none) from the case of
an unknown specified directive (D_unknown). This is reflected in
different error messages.
Furthermore, change the special case symbols to lower case in case we
ever have a directive called [none] or [unknown].

Split out the global directives into a separate section, that allows
the switch() in the main code to be slightly faster.
