GET /rest/svc/deviceid
======================

Verifies and formats a device ID. Accepts all currently valid formats
(52 or 56 characters with or without separators, upper or lower case,
with trivial substitutions). Takes one parameter, ``id``, and returns
either a valid device ID in modern format, or an error.
