This restores go.errors from before3af0d79along with a fixed up version of the bisonerrors AWK script, translated to Go. However, this means Yyerror needs access to the yacc parser's state, which is currently private. To workaround that, add a "state" accessor method like the Lookahead method added inc7fa3c6. Update issue #9968.
