Upstream patch
- to diagnose readdir() failures in fts-based utilities,
- fixes boo#984910,
- to be removed with coreutils > v8.25,
- consists of the following parts:
1. the fix in thee gnulib submodule
2. the NEWS entry
3. the test added to verify the fix.
4. Upstream coreutils commit to fix the test on 32-bit
----------------------------------------------------------------------
1. Upstream gnulib submodule commit:
http://git.sv.gnu.org/cgit/gnulib.git/commit/?id=6835fc458f30

>From 6835fc458f30b94f15d69c35a79cbc2dfabe2d06 Mon Sep 17 00:00:00 2001

Date: Wed, 22 Jun 2016 13:49:53 +0100
Subject: [PATCH] fts: handle readdir() errors
* lib/fts.c (fts_build): readdir(3) returns NULL when finished,
but also upon error when it will also set errno. Therefore
flag the error case from readdir(). We treat the case where
no items are read the same as if the dir can't be accessed,
i.e. by setting fts_errno to FTS_DNR.
The bug was initially reported by Peter Benie
http://bugzilla.opensuse.org/show_bug.cgi?id=984910
where it was mentioned that readdir() may fail
when an NFS server has a poor readdir cookie implementation.
----------------------------------------------------------------------
2. Upstream coreutils commit:
http://git.sv.gnu.org/cgit/coreutils.git/commit/?id=ef9650170f79
Take the NEWS change only, as the fix in fts.c was already
pulled in with the above gnulib commit.

Subject: [PATCH] all: update gnulib submodule and tests/init.sh to latest
* NEWS: Specifically mention the fts readdir() fix.
----------------------------------------------------------------------
3. Upstream coreutils commit to add a test:
http://git.sv.gnu.org/cgit/coreutils.git/commit/?id=26616776c0c6

Date: Sun, 26 Jun 2016 19:07:45 +0100
Subject: [PATCH] tests: verify that fts diagnoses readdir() failures
* tests/rm/rm-readdir-fail.sh: A new test to simulate readdir()
failing immediately or after returning a few entries, and verifying
that rm does the appropriate thing.
This was initially reported at:
http://bugzilla.opensuse.org/show_bug.cgi?id=984910
where it was mentioned that readdir() may fail
when an NFS server has a poor readdir cookie implementation.
----------------------------------------------------------------------
4. Upstream coreutils commit to fix the test on 32-bit
http://git.sv.gnu.org/cgit/coreutils.git/commit/?id=54c1397510cb
>From 54c1397510cb08433680b5b7da46a8201770e9ee Mon Sep 17 00:00:00 2001

Date: Wed, 6 Jul 2016 18:08:32 +0100
Subject: [PATCH] tests: avoid false failure on 32 bit in readdir() test
* tests/rm/rm-readdir-fail.sh: Since we use the returned dirent
from the readdir wrapper it must be the correct type and not
just cast. Therefore setup so that we only have to define a
wrapper for readdir(), which works appropriately on 32 and 64 bit.
Issue reported by Bernhard Voelker, where rm was seen to invoke
rmdir() on invalid file names.
