Reland 110355 - Use shared D3D9 texture to transport the compositor's backing buffer to the browser process for presentation.

Implemented ImageTransportSurface for Linux (without texture sharing), XP, Vista and 7. XP. The non-texture sharing Linux and XP paths just present directly to the compositing child window owned by the browser process as before.

PassThroughImageTransportSurface still needs a proper name. I will move it into its own file once that is decided.

I moved AcceleratedSurfaceBuffersSwapped outside of the platform specific ifdefs and made the signature the same on all platforms for greater consistency.

I removed the code related to sharing surfaces between processes and synchronizing resize and swapping out of GpuCommandBufferStub. It is all now in ImageTransportSurface implementations.

FYI, please tag all overriding functions with OVERRIDE. (I'm fixing this one in
a patch to come.)
