    systemd-updates: Do not exit with an error for a race condition
    
    The daemon plugin pk-plugin-systemd-update deletes the /var/lib/PackageKit/prepared-update
    file if any transaction is done that affects the prepared state.
    This includes the offline-update process itself.
    
    If the daemon deletes the file before the pk-offline-update process tries to do
    it a warning is shown and the systemd unit fails.

    Raise the package process threshold to 5000
    
    TeXLive has officially jumped the shark, and it's quite plausible to have > 2500
    updates in one transaction now.

    yum: Use yb.downloadPkgs() to download updates
    
    There were two bugs here:
    
    - Using repo.getPackage() did not check the package checksum, only the size,
      so it was possible to download a corrupt package and then not be able to
      apply the updates
    
    - By restricting to TS_UPDATE and TS_INSTALL we were ignoring any package that
      was obsoleting another which could miss out packages.
    
    Many thanks to Zdenek Pavlas for all the help in finding these issues.
