Are renames likely to be a common quirk on the road to libgpiod
conversion?

I admit I sort of expected it to be common enough that there would be
one rename quirk in the code supported by an alphabetized string table.
Such a table would certainly still provoke troublesome merges but ones
that are trivially resolved.
