Fix browser rendering issue: pure color tiles are rendered black

The “pure color tile” optimization finds the pure-color tiles and
then draws the tiles simply with the color (otherwise the texture).

But the RGBA color pointer type is char, which may overflow when
the value is larger than 127. In such case, the tiles in question
are rendered black, because of the wrong color. This bug is fixed
by defining the pointer as unsigned char.

Fix memory leak caused by CSSRuleList wrapper

Accessing cssrulelist in javascript will create a new
CSSRuleList object and wrapper JS object. The wrapper
JS object will be added into hidden array in parent JS
object which is alive during the whole execution. Thus
memory leak happens (CSSRuleList in webkit, wrapper object
and weak global handle in v8).

Cherry pick 2 patches from upstream solves the problem:

http://trac.webkit.org/changeset/90949

This patch changes hidden reference from array to named
property. So new wrapper will replace old wrappper. But the
memory leak still exists because the CSSRuleList wrapper
will be added into an object group of current document. So
they will still be alive during execution.

http://trac.webkit.org/changeset/91256

This patch avoids to adding CSSRuleList wrapper into document
object group. Combined with the first patch, it can resolve
the memory leak problem.

Crash on Orange media portal

Visit orange.deezer.com, press tab marked "My Music".
Browser crashes every time.

Pressing the button will trigger a re-layout of the page.
This in turn will cause some rendering nodes of type
RenderLayer to be removed from the rendering tree.
When such a node is removed, it is important to also
update certain lists in ancestor nodes that may hold references
to this node. A node that may hold such a reference is
identified as being a "stacking context".

However, in Android, when the symbol ENABLE_COMPOSITED_FIXED_ELEMENTS
is defined, the definition of what is a stacking context
is expanded. In this case, a node that is a stacking context
and holds references to descendants, changes one of the conditions
that form part of Android's expanded stacking context definition.
So, now it is no longer a stacking context, but the reference list
is not deleted/updated. When the descendant node is removed a
search for an ancestral stacking context is made, but it will
not find this node since it is no longer a stacking context.

The solution is to make sure that the list of references is
updated/cleared whenever the node changes a condition that
may cause its status as a stacking context to also change.

Make CachedResource take a ResourceRequest instead of just a url string.

        Reviewed by Adam Barth.

        Change CachedResources to take a ResourceRequest instead of
        a url in their constructors and provide a very minimal set of
        cases for avoiding reusing a CachedResource. The ResourceRequest
        part of this change requires pushing responsibility
        for calling Document::completeURL() to the caller, instead of
        CachedResourceLoader, since ResourceRequest ASSERTs if it
        is constructed with an invalid url.

        HTMLVideoElement::currentSrc() should return a KURL
        https://bugs.webkit.org/show_bug.cgi?id=61578

        I suspect we got into this mess because the author of this code didn't
        know about the URL attribute in WebKit IDL, which is super useful!

        Bad news: The line of code in question seems to have another bug, which
        I've documented in a FIXME.  Let the yak shaving continue!

        * html/HTMLMediaElement.cpp:
        (WebCore::urlForLogging):
        (WebCore::HTMLMediaElement::loadResource):
        (WebCore::HTMLMediaElement::isSafeToLoadURL):
        (WebCore::HTMLMediaElement::selectNextSourceChild):
        (WebCore::HTMLMediaElement::getPluginProxyParams):

        (WebCore::CanvasRenderingContext::checkOrigin):
        * rendering/HitTestResult.cpp:
        (WebCore::HitTestResult::absoluteMediaURL):
            - This complete URL call was unnecessary because currentSrc is
              already absolute.

        Updated origin-clean-conformance.html to track upstream version in
        Khronos repository. Added new layout tests mirroring those added
        in bug 61015 which verify that new CORS support for images is
        working in the context of WebGL.

        Verified new tests in WebKit and Chromium. Skipped tests on
        platforms where WebGL is disabled.

Runtime enablement of WebGL logs

Allows enabling WebGL method level logging using:

adb shell setprop debug.webgl 1

Adding WebGL FPS timing to logs

Samples WebGL average FPS every 15 frames and outputs to WebGL debug log.
TODO: Add setting to browser debug settings that overlays FPS on web
pages.

Postpone deleteRenderbuffer/deleteTexture until all framebuffer attachment points are removed.

Source/WebCore:

Use WebGLObject's attachment count mechanism to track if a renderbuffer/texture
is still attached to framebuffers, and if its deletion should be delated or not.
