Jim Chen 3587a0edd6 Bug 1306083 - 1. Use AndroidCompositorWidget to access GeckoLayerClient; r=kats
Add AndroidCompositorWidget to act as the intermediary between gfx code
and GeckoLayerClient, in place of AndroidBridge. AndroidCompositorWidget
currently inherits from InProcessCompositorWidget, but when Android
eventually supports OOP compositing, it will be made to inherit from
CompositorWidget directly.
