[GTK] LayerTreeHostGtk is creating a software scene graph
https://bugs.webkit.org/show_bug.cgi?id=131471

Reviewed by Sergio Villar Senin.

At some point, a regression was introduced that sent the GTK+ WebKit2 scenegraph down the
software route. The rest of the file depends on the fact that the TextureMapper is the OpenGL
variety, so we should force that explicitly. This is causing crashes locally and soon we
should be able to test this directly.

* WebProcess/WebPage/gtk/LayerTreeHostGtk.cpp:
(WebKit::LayerTreeHostGtk::initialize): Force the use of the OpenGL scenegraph.

Patch by Youenn Fablet <youenn.fablet@crf.canon.fr> on 2014-04-10
Reviewed by Philippe Normand.

Source/WebCore:

Added CORS access control check to media sources when crossorigin attribute is set.

Added getter to CORS access control check status (used to compute whether the stream is tainted or not).
Related test is http/tests/security/video-cross-origin-readback.html.

Disabled access to cross-origin streams that fail CORS check when crossorigin attribute is set.
Related test is http/tests/security/video-cross-origin-accessfailure.html.

       http/tests/security/video-cross-origin-accesssameorigin.html

* platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.cpp:
(WebCore::MediaPlayerPrivateGStreamer::didPassCORSAccessCheck): Return whether media is cross-origin (tainted) or not by querying the gstreamer source layer.
* platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.h: Added MediaPlayerPrivateGStreamer::didPassCORSAccessCheck declaration.
* platform/graphics/gstreamer/WebKitWebSourceGStreamer.cpp:
(webKitWebSrcStart): Passed CORS mode parameter to the streaming client. In case of CORS check failure, stop the resource loading.
(webKitSrcPassedCORSAccessCheck): Return whether CORS access control check was done and successful.
(StreamingClient::handleResponseReceived): Take a parameter to assign the CORS access control check result.
(CachedResourceStreamingClient::CachedResourceStreamingClient): Updated setting of the ResourceLoaderOptions according CORS mode.
(CachedResourceStreamingClient::responseReceived): Check CORS and pass result to handleResponseReceived.
(ResourceHandleStreamingClient::didReceiveResponse): No CORS check.
* platform/graphics/gstreamer/WebKitWebSourceGStreamer.h: Added webKitSrcPassedCORSAccessCheck declaration.

LayoutTests:

http/tests/security/video-cross-origin-accessfailure.html verifies that cross-origin streams that fail CORS check
are not played when crossorigin attribute is set.
 http/tests/security/video-cross-origin-accesssameorigin.html verifies that access to same-origin streams
are played when crossorigin attribute is set.
