        Dynamically inserting CSS rule with @media query fails with DOM Exception 12
        <http://bugs.webkit.org/show_bug.cgi?id=15986>

        Reviewed by Darin.

        Allow any valid rule (@font-face, @import, @media, @page or style) to be
        parsed when using CSSStyleSheet.insertRule().  Previously only import and
        style rules were allowed.  Note that @page rules always throw an exception
        because they're not implemented yet, so no test case was added for them.

        Tests: fast/css/insertRule-font-face.html
               fast/css/insertRule-media.html

        * css/CSSGrammar.y: Extracted 'valid_rule' out of 'rule'.  Renamed
        'ruleset_or_import' to 'valid_rule_or_import' and changed its definition.
