       LP: #992468, LP: #992982, LP: #1000172, LP: #1000758)
     - USB backend based on the maintained libusb 1.0.x with support for
       bi-directional communication
     - Fixes on SNMP-based supply level reporting
     - PostScript prtinter auto-configuration reliable now
     - Several fixes on PostScript, SSL, authenticated printing, and
       networking issues
  * debian/patches/ipp-fixes-1.5.3.patch,
    debian/patches/fix-empty-translations.patch,
    debian/patches/ppd-cache-fix-crash.patch,
    debian/patches/commandtops-make-robust-against-broken-postscript.patch,
    debian/patches/cups-polld-reconnect.patch,
    debian/patches/usb-backend-libusb-1.0.patch,
    debian/patches/usb-backend-backchannel-support.patch: Removed patches which
    got included upstream.
  * debian/patches/fix-supply-level-computation-for-percent-supply-unit.patch,
    debian/patches/fix-supply-levels-for-enumerated-prtmarkersupplieslevel.patch,
    debian/patches/fix-status-reports-when-supply-levels-grow.patch,
    debian/patches/add-status-reports-for-full-waste-trays-and-cleaner-unit-eol.patch,
    debian/patches/match-marker-colorants-which-use-non-standard-string.patch,
    debian/patches/truncate-marker-supply-names-at-comma.patch: Removed supply
    level report fixes. This got solved differently upstream.
  * debian/patches/do-not-suppress-inputslot-setting-with-empty-ap-d-inputslot.patch:
    Removed, problem solved differently upstream.
  * debian/patches/cups-avahi.patch: Manually regenerated to adapt to upstream
    changes.
  * debian/patches/ppd-poll-with-client-conf.patch,
    debian/patches/colord-support.patch,
    debian/patches/airprint-support.patch,
    debian/patches/no-conffile-timestamp.patch,
    debian/patches/drop_unnecessary_dependencies.patch,
    debian/patches/read-embedded-options-from-incoming-postscript-and-add-to-ipp-attrs.patch,
    debian/patches/show-compile-command-lines.patch: Refreshed using quilt.
  * debian/patches/usb-backend-busy-loop-fix.patch: Correct loops to repeat
    claiming interfaces on USB devices when they are busy. Before, hitting busy
    state made the device opening function error out without comment
    (LP: #987485).
  * debian/patches/usb-backend-detach-usblp-earlier-crash-guards.patch: Protect
    against crashes by checking error codes of libusb functions (LP: #997040)
    and detach usblp kernel module in an earlier stage when opening a device
    (LP: #987485, LP: #997040).
  * debian/patches/usb-backend-initialize-usblp-attached-state.patch: Initialize
    usblp_attached field in printer data structure to assure that detaching
    and re-attaching the usblp kernel module is always done correctly
    (LP: #902535, LP: #959676, LP: #960666, LP: #987485,
    LP: #995111, LP: #997040, LP: #1000253, LP: #1001028).
  * debian/patches/install-sh-remove-bashism.patch: Removed bashism.
  * debian/local/blacklist-cups-usblp.conf, debian/cups.postinst,
    debian/cups.install: Blacklist the "usblp" kernel module again. We have
    now a full-featured USB backend based on the maintained libusb 1.0.x
    and so we can acess printers always through the raw USB devices making
    the module deprecated. Detaching the kernel module for each access causes
    a lot of problems: LP: #902535, LP: #959676, LP: #960666, LP: #987485,
    LP: #995111, LP: #997040, LP: #1000253, LP: #1001028.

  * debian/cups.{preinst,postinst,postrm}: Drop the removal of obsolete
    /etc/modprobe.d/blacklist-cups-usblp.conf conffile, as this file is
    reintroduced now.
