Make the private variables for various lexical analyzers static, so

Make the private variables for various lexical analyzers static, so
that we don't have all the lexical analyzers in libethereal share them
(note that they're already static in radius_dict.l, so they weren't
sharing with any other lexical analyzer), and so that OS X 10.3.9's
run-time linker doesn't get upset at finding them defined in libethereal
and the MATE plugin.

Fix up indentation.
