What to do about gnulib libio dependencies?

I think we should include these APIs, disregarding their quality, merely 
for harm reduction purposes.  (The same thing could be said about 
strlcpy/strlcat.)

We don't have much choice here: If we don't provide these interfaces, 
gnulib will continue to poke at our internals.  It's extremely unlikely 
that all those copies of these support routines will be dropped, ever, 
so we need to keep support for existing binaries, anyway, and that will 
be easier if we have the requirements documented in the glibc source 
code, through our own (matching) implementation.

Thanks,
Florian
