Pablo Correa Gómez c87b926a53 Move logic to check if deviceinfo file exists to pkgs/deviceinfo (MR 37)
This is mostly a preparatory commit to later be able to read the
deviceinfo from multiple places. It has a bit better encapsulation,
and makes the functions methods, so that they can update deviceinfo
file in-place.
