[X2Go-Dev] Some backports

[Ulrich Sibiller]

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/4f58fbb6c6b971046926a50bfaa92fe331d946b9

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?
