don't use new to create parser object
* topleve.cc (main_loop): Don't use new to create parser object.
Change all uses. Don't use unwind protect to clean up the parser
object.
* input.cc (get_debug_input): Likewise.
* oct-parse.in.yy (parse_fcn_file, eval_string): Likewise.
(yyerror, bison_error, %parse-param): Pass octave_parser argument by
reference, not pointer.
(#define curr_lexer): Update definition.
