[Bug-gnulib] census of gnulib versus libc files; strtoul.c now generated

[Paul Eggert]

I took a census of gnulib files compared to libc files and added the
following patch to config/srclist.txt to report my results.  The only
non-comment change here is to add strtoul.c, which already matched
exactly (except for white space and for GPL <-> LGPL).  I regenerated
strtoul.c while I was at it.

In the longer run I'd like to merge some of these files so that the
gnulib and libc versions match exactly (except for GPL <-> LGPL), but
first things first.

        * srclist.txt: Sort sublists.  Add $LIBCSRC/sysdeps/generic/strtoul.c.
        In comments, add more libc files that differ from gnulib for one
        reason or another; we'd like this list to be smaller but for now
        let's document what we have.
