SystemUI demo mode.

Control the status bar visuals via a simple intent protocol.
Useful for comprehensive visual testing reachable assets
and the various bar modes.

Protected behind a global system setting.  To enable:
  adb shell settings put global sysui_demo_allowed 1

Remove obsolete sync failing asset, and tighten up
BluetoothController to represent reality.
