  <description>Avoid annoying error message due to deprecated ConfigParser.readfp
readfp is deprecated since 3.2 and obsolete since 3.12 of the config parser, but still used on the first try of reading the config file. With this change read_file is tried first.

The change basically reworks hplip-base-fix-error-in-ConfigBase-handling.patch - it would be cleaner to replace that patch (I would be happy to provide it, but I was not sure if this fits to the workflow.)</description>
