yacc: attempt to keep line numbers right for yyparse()
as the generated parser intermixes lines from .y source
and the parser text, the line source/lineno for yyparse()
shows up wrong in the debugger. to make stack traces a
bit less crazy, put a #line 1 "/sys/lib/yaccpar" before
copying in the parser text.
