        Escape control characters in CSS string value when it is serialilzed.

        When WebKit serializes a CSS string value that contains binary characters
        ('\0\1\2' for example), it did not escape these characters. As a result,
        users got (invisible) control characters through scripts. This change fixes
        this issue.

        As a side effect, two separate codes for escaping CSS strings are merged, and
        become a public function (quoteCSSString).

        CSS string value is not correctly serialized when it contains binary characters
