Parse media attributes and CSSOM media text as media_query_list.
This is per HTML5 and CSSOM specifications.
This change makes the remaining fails in the W3C Media Queries test suite pass.
Some resulting changes:
- Brackets/parentheses balanced correctly.
- Queries split between correct commas.
- Spaces is an empty media query list like the empty string.
- Unexpected EOF like missing parentheses makes the query valid as per CSS21
spec.
- Syntax errors become "not all" as per CSSMQ spec.
- Renamed @-webkit-mediaquery to @-internal-mediaquery to be consistent with
other internal @-rules.
- Removed MediaQueryParserMode which is now the same for all MQ parsing.
