Comment 6 for bug 2048876

I have attempted a draft fix for this issue in the attached debdiff. It introduces a new configuration directive "disallowname" that can make a source name configuration entry ineffective.

Please let me know if my attached changes seem feasible to be adopted, I'd be happy to discuss and iterate them further, and finally work on proposing them to the debian package.
The approach in the attached debdiff might complement the packaging solution described by @paride in https://bugs.launchpad.net/ubuntu/+source/chrony/+bug/2048876/comments/3. This is because, with the proposed debdiff, the source configuration for chrony can be modified without touching any package installed files.
