cups 1.5.3-3 source package in Ubuntu

Changelog

cups (1.5.3-3) experimental; urgency=low

  * debian/patches/usb-backend-further-enhancements.patch: Added latest
    development work on the libusb-based USB backend:
     - Support for uni-directional devices, both protocol-1 devices and
       devices where no read endpoint is found.
     - Soft reset specific to the "PRINTER" device class. This allows a
       reset without reconnecting.
     - When closing the device, it will also get reset to its original
       configuration, before re-attaching the usblp kernel module. Do not
       restore the configuration setting when the old configuration was zero,
       as zero means "unconfigured".
     - Added option "usb-unidir" to force the backend into uni-directional
       mode. This allows to work around problems with bi-di communications,
       especially also a delay at the end of the job caused by closing the
       read channel (happens only for some devices, LP: #1001028). Also
       useful for debugging.
     - Added the quirk management of the usblp kernel module. So the problems
       of all printers which were worked around in the kernel module are
       also worked around in the libusb-based CUPS backend now (LP: #1000253).
     - Added new quirk type to quirk manager: Printers for which the usblp
       kernel module should not get reattached after printing a job
       (LP: #1000253, perhaps also LP: #995111).
     - Added additional quirks for the Prolific Technology USB -> Parallel
       adapter, as the adapter needs uni-directional mode to be forced and
       also does not like re-attaching the usblp kernel module after the
       job (last third of last page gets cut off, re-attaching probably
       sends a reset to the printer while there is still data to be printed
       in the printer's internal buffer (LP: #987485).
     - Added the command line option "usb-no-reattach". With the option set
       the usblp kernel module does not get reattached after a job has been
       printed. Some printers cut off the end of the job or even crash by
       re-attaching the module. This is a development/debug mode to test
       whether re-attaching was the culprit of a problem. Users should
       report such issues so that their printers can get added to the quirk
       list.
     - Some extra debug messages.
     - Added a missing libusb_free_config_descriptor().
    This patch is submitted upstream as CUPS STR #4128.
  * debian/patches/add-ipp-backend-of-cups-1.4.patch, debian/cups.config,
    debian/cups.lintian-overrides, debian/cups.postinst, debian/cups.prerm,
    debian/cups.templates: Add the IPP backend of CUPS 1.4.x to the current
    CUPS package as independent backend "ipp14". Some devices (like the
    LiveBox 2) do not work with the current IPP backend (LP: #945028,
    LP: #973270, LP: #990734, LP: #992468, LP: #992982).
  * debian/patches/ipp-backend-cups-1.5.4-fixes.patch: Backported latest
    fixes on the IPP backend from upstream.
  * debian/local/blacklist-cups-usblp.conf, debian/cups.postinst,
    debian/cups.install, debian/cups.preinst, debian/cups.postinst,
    debian/cups.postrm: As we have vastly improved the USB backend, we try to
    work without blacklisting the usblp kernel module again during the
    development cycle of Ubuntu Quantal.
