This could potentially eventually become a public GLib API, but there
doesn’t seem to be a huge need for it right now (e.g. this file contains
the only use of `/proc/self/fd/%d` in GLib), so let’s keep it private
for now and avoid committing to API stability just yet.
This gives time for other platforms to add their platform-specific
implementations for it too, if they need. I’ve added a couple of
pointers to what I *think* the right APIs might be, from my research,
but I have not prototyped those implementations.
