Use new paradigm for hdr file double inclusion guard
We changed to use symbols not likely to be used by non-Perl code that could conflict, and which have trailing underbars, so they don't look like a regular Perl #define. See https://rt.perl.org/Ticket/Display.html?id=131110 There are many more header files which are not guarded.
