More archive related code will be added shortly, so having a separate file makes more sense. The utils.py imports the functions from archive.py, so that existing callers don't need to be modified. This avoids redundant code churn until later in the series when all calls will be adapted for other reasons. Signed-off-by: Daniel P.
