Aha, sorry I had missed that. I assumed you wanted to see the precise
steps that transformed the dwarf branch dwarfstrings.c to what we want
to have with full usage of know-dwarf macros. I am happy to collapse
those intermediate commits again.

I haven't looked whether there are other places where the known-dwarf
macros could be used. But I suspect that the main usage is precisely
the reuse of string form functions like in readelf and the tests.
And that is also why I did them, because when I write things using
libdw I always end up writing something to detect whether DWARF codes
are known and turn them into some string representation to show lists
or generate (error) messages. I suspect there are more users like that
out there.

That is consistent. It will result in 17 new tiny files though.
