The offending commit has been in the tree for a week. So I applied Andrii's revert of that change. It reintroduced the build dependency issue, but we lived with it for long time, so we can take time to fix it cleanly. I suggest to focus on that build dependency first.

I'm not sure it's a good idea. It feels nice, but think of a message we're sending to everyone. We will get spamed with question: does bpf community require all libbpf users to use bpf/ prefix ? What should be our answer? Require or recommend? If require.. what for? It works as-is. If recommend then why suddenly we're changing all files in selftests and samples? There is no good answer here. I think we should leave the things as-is. And fix build dep differently.
Patches 1-3 are still worth doing.
