bug#18360: Modularize recent qsort_r additions

[Paul Eggert]

Tags: patch

The recent changes to have Emacs use qsort_r look good except for the 
forest of #ifdefs in Emacs proper.  Attached is a proposed patch to 
migrate that stuff into Gnulib.  As usual most of this patch is 
automatically generated; fns.c contains the crucial hand-generated 
stuff.  I have not tested this on Microsoft Windows and so am posting it 
here first to give Eli a heads-up.
