Hey all, now that archlinux is supporting debuginfod, I have finally tried it out. It's such a game changer, many thanks for everyone involved in working on this!
Now to my question: In applications using elfutils, we will now automatically download debug information when DEBUGINFOD_URLS is defined. But doing that can take a very long time. I would like to give the user feedback about this situation and ideally provide a means to cancel the download. Looking at `debuginfod.h` I `debuginfod_set_progressfn` which looks ideal. But how do I access the default `debuginfod_client *` which seems to exist without me ever calling `debuginfod_begin` anywhere? Or do I need to create a new client here via `debuginfod_begin`? Then, how would I cancel an ongoing download job? GDB seems to do that when I press `CTRL+C`, but I do not see any API I could use for that purpose? Finally, what is the recommended way to check whether debuginfod is available? Should one rely on the build system to discover the `debuginfod.h` header file, or is some other compile time check suggested to detect it? I'm asking, because while I want to add the above API to get a better debuginfod experience, I do not necessarily want to raise the minimum elfutils version requirement just for that purpose.
