branches/zip: Make the changes to pars0grm.c that were promised in r2276.

pars/pars0grm.h: Remove.  The primary file is include/pars0grm.h.

pars/make_bison.sh: Add from trunk.  Somehow, this file was not merged
at the same time with make_flex.sh.  Add sed magic for replacing the
file name and for hiding yychars, yynerrs, yylval, and yyparse.

pars/pars0grm.c: Apply the changes made by make_bison.sh.
