Support the usage of CORS for WebGL and the 2D canvas

Factor CORS request preparation out of DocumentThreadableLoader

        Factor CORS request preparation out of DocumentThreadableLoader
        https://bugs.webkit.org/show_bug.cgi?id=61209

        DocumentThreadableLoader has two jobs:

        1) Proxy loads between threads.
        2) Run the CORS state machine.

        This patch begins the work of separating those concerns, allowing CORS
        to be used elsewhere in the loading pipeline.  In particular, this
        patch moves knowledge of how to prepare CORS requests out of
        DocumentThreadableLoder.

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

2011-05-24  Nate Chapin  <japhet@chromium.org>

        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.

WebGL implementation for Android

Implementation of WebGL in Android WebKit. Exposes a low level 3D
graphics API based on OpenGL ES 2.0 to JavaScript. WebGL is not compiled
by default. It can be enabled by setting ENABLE_WEBGL = true in your
device BoardConfig.mk or directly in external/webkit/Android.mk. It is
also disabled by default (in WebSettings.cpp) as required by Khronos
until it reaches 100% conformance.
