implement activity blocking

- monitor activity launch and shut it down if
  car is not parked and if the app is not allowed.
- Launch blocking activity for unsafe app.
- Blocking activity stays up to timeout (3 secs) and
  finish itself if there is safe app behind.
  If safe app is not there, launch home. If home is
  not safe either. stay.
- allow OEMs to give static whitelist as overlay.
