[X2Go-Dev] Some backports

Hi,

while testing my randr code I found a bug in the randr extension which had been fixed upstream long time ago. I took the chance to look over the current randr code, found some more fixes and have backported some of them in this commit: https://github.com/uli42/nx-libs/commit/4f58fbb6c6b971046926a50bfaa92fe331d9...

This code is of interest for 3.5.x as well as 3.6.x. My question: What is the best way to provide those fixes? For now I have one commit for all of them. I could also generate separate commits for every backport. Also, is it ok to mark the fixes by a comment as I did or should this information better be moved to the commit log?
