local pv.

yypvars*. No longer cast to void* on return.

(global scope): Do not declare b4_declare_parser_variables if
push or pure mode.
(yypushparse): Add b4_declare_parser_variables.
Init new local variables, and remove init code for removed
yypvars variables.
(yyparse): Delete.
* tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
and yyparse for other modes.
(AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
* tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
(AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
(AT_PURE_LEX_IF): True if pure or push parser.
(b4_yyssa, b4_yyerror_range): New macros.
(struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
(yypvarsinit): Remove init of removed fields.
(yypushparse): Remove use of removed fields; use new macros instead.
in a push parser. Reindent slightly to match yacc.c better.
