Remove the Media Query "forward compatibly syntax" support in alignment with HTML5 spec

Remove the Media Query "forward compatibly syntax" support in alignment with HTML5 spec

Media queries, as described in the Media Queries Level 3 specification, build
on the mechanism outlined in HTML4. The syntax of media queries fit into the
media type syntax reserved in HTML4. The media attribute of HTML4 also exists
in XHTML and generic XML. The same syntax can also be used inside in the
‘@media’ and ‘@import’ rules of CSS.

However, the parsing rules for media queries are incompatible with those of
HTML4 so that they are consistent with those of media queries used in CSS.

HTML5 references the Media Queries specification directly and thus updates the
rules for HTML.

This change is in alignment with Presto and Gecko behavior.

Rubber stamp.

I did not look much at the modified test-cases.

File Source/core/css/MediaList.cpp (right):

https://codereview.chromium.org/16325005/diff/1/Source/core/css/MediaList.cpp...
Source/core/css/MediaList.cpp:44: * and generic XML. The same syntax can also be
used inside in the ‘@media’ and
extraneous "in" ("...inside in the @media...").

You also use '’' for quoting, which seems to be a non-ASCII character

https://codereview.chromium.org/16325005/diff/1/Source/core/css/MediaList.cpp...
Source/core/css/MediaList.cpp:48: * so that they are consistent with those of
media queries used in CSS.
"so that" sounds a bit confusing here. Were you trying to say that even though
the parsing rules are incompatible with those specified in HTML4, they are
consistent with those of media queries used in CSS? Then just replace "so that
they" by "and" (...are incompatible ... and are consistent...)
