ipp-usb compatibility issues with existing/future software in distributions

To ease up using ipp-usb in the system by default, we should try to tackle and track issues which other apps have if ipp-usb is on system.

There are:

1. any classic USB printer backends (CUPS usb, hplip hp, gutenprint gutenprint53+usb and more proprietary ones) list the device even if its interface is claimed by ipp-usb, which means the newly installed printer won't work, even if the device was advertised by the backend
2. any printer applications list the device even if it claimed by ipp-usb, thus unavailable
3. any already installed USB printers from the past which interface is now claimed by ipp-usb don't work - aka migration solution
4. there is duplicity in the scanner's list, if the scanner/multifunction device is supported by ipp-usb and by a classic driver, but the classic driver won't work because ipp-usb claims the device's interface.

Ad 1.

• CUPS tracks the issue - usb backend will check mDNS comm and if the found device is on mDNS, ignore this device in usb backend
• the similar solution can be done in other open source driver packages - probably gutenprint will be a possible candidate because it has responsive upstream

Ad 2.

• we can get the similar fix as for CUPS issue - I created a new issue for PAPPL https://github.com/michaelrsweet/pappl/issues/211

Ad 3.

• already being covered in https://github.com/OpenPrinting/ipp-usb/issues/50

Ad 4.

• I've reported the issue to SANE project, proposing the CUPS solution. I mentioned an idea for ipp-usb writing a file with claimed devices in /tmp, and function in SANE library, libusb_scan_devices() will read it and ignore devices mentioned there
• issue https://gitlab.com/sane-project/backends/-/issues/603

Start by reviewing the compatibility cases and linked CUPS, PAPPL, ipp-usb issue 50, and SANE issues in the issue body. The issue does not name repository files or tests; completion would require defining and coordinating fixes for the listed printer and scanner integration problems.
