cups-filters 1.14.1

New point version:

CHANGES IN V1.14.1

        - cups-browsed: Do correct removal of printer entry handling
          duplicates correctly also when a legacy CUPS-broadcasted
          printer disappears or a printer remaining from the last
          session does not appear again.
        - cups-browsed: Use getline() instead of fgets() to read saved
          option settings. This is less crash-prone (Ubuntu bug
          #1658833).
        - cups-browsed: Improved error logging when saving option
          settings.
        - cups-browsed: Added NULL checks for generate_local_queue()
          and create_local_queue() functions.
        - cups-browsed: When accessing local CUPS queues use always
          the correct port of the CUPS daemon we are attached to.
        - cups-browsed: Check whether a connection to the local CUPS
          daemon actually happened before using it (Ubuntu bug
          #1644049).
        - cups-browsed: Set unused fields of printer record to NULL
          when tranfering data from the record of a duplicate printer
          to the record of a disappeared one.
        - cups-browsed: Simplify removal of all queues on shutdown or
          stop of Avahi.
        - cups-browsed: When creating a record for a discovered
          printer set it all zero before filling it in, to assure
          that no field is in an undefined state.
        - cups-browsed: All functions which are called via Glib
          functions or otherwise event-triggered log now in which
          thread they are running. This way one can see whether
          problems can be caused by concurrent access to global
          resources.
        - cups-browsed: Do not check whether the DNS-SD event is from
          the local machine in the browse_callback() function. We
          cannot check the port here.
        - cups-browsed: Added more NULL checks to Avahi callback
          functions.
        - cups-browsed: Added NULL check to avoid crashes in the Avahi
          resolver callback (Ubuntu bug #1696967).
        - libcupsfilters: Let PPD generator do case-insensitive
          comparisons for PWG Raster color spaces, as some printers
          (Epson) do not use the standard-conforming all-lowercase
          form for them (CUPS Issue #4998).
