#4 xcwcp could use a port to Qt6

[Thomas Beierlein]

xcwcp at the moment is not compatible with Qt6. Support for Qt5 gets dropped more and more. So an actual version supporting Qt6 would be much appreciated in the coming month.

See https://bugs.gentoo.org/948836 for some more details.

I did some work on it myself and have a working version. I can provide the needed patches to start going. Feel free to send me a mail about it.
