    - avoid sending overly long job names in IPP requests
    
    Some clients (e.g. Google Drive PDF Viewer) create hilariously long
    document titles (same hash?) when they send jobs to CUPS. CUPS uses that
    as job-name when sending IPP requests to printers and not all printers
    can accept that and reject the job. Trim job-title at arbitrary number
    of 127 characters to make all this work.
