This implements the new system for Graphics2D only.

This works by adding a new thunk layer that will forward to an "API" that's either per-instance (function APIs) or per-resource (resource APIs). The proxying and such is then implemented in terms of this C++ API.

Ideally the trackers of the PP_Resource/PP_Instance -> object mapping would be shared between the plugin and renderer processes. To keep this patch under control, I did this as a virtual base class which is implemented by ppapi::proxy::PluginResourceTracker and webkit::ppapi::ResourceTracker. Later, the functionality of these objects should be shared in a common tracker class.

Still to do it a lot of cleanup and merging of things. Also, the namespaces are a bit out of control.
