css: Rewrite the parser Instead of relying on GScanner and its idea of syntax, code up a parser that obeys the CSS spec. This also has the great side effect of reporting correct line numbers and positions. Also included is a reorganization of the returned error values. Instead of error values describing what type of syntax error was returned, the code just returns SYNTAX_ERROR. Other messages exist for when actual values don't work or when errors shouldn't be fatal due to backwards compatibility.
