HUD does not support unity8's window stack API

The crux of the problem here is that HUD was talking to the SurfaceFlinger based Unity Platform API.

We HUD to talk to unity8's new window stack API. On the desktop we will construct a bridge daemon that adapts from the BAMF API to the unity8 API.

I got this crash right after booting the device with mir enabled.
