      Split general policy into public and private components. · cc39f637
      dcashman authored
      Divide policy into public and private components.  This is the first
      step in splitting the policy creation for platform and non-platform
      policies.  The policy in the public directory will be exported for use
      in non-platform policy creation.  Backwards compatibility with it will
      be achieved by converting the exported policy into attribute-based
      policy when included as part of the non-platform policy and a mapping
      file will be maintained to be included with the platform policy that
      maps exported attributes of previous versions to the current platform
      version.
      
      Eventually we would like to create a clear interface between the
      platform and non-platform device components so that the exported policy,
      and the need for attributes is minimal.  For now, almost all types and
      avrules are left in public.
      
      Test: Tested by building policy and running on device.
