bfb4f5c8b7 tests: avoid a FP on aarch64 when comparing env/printenv output
The following test fails on aarch64 on openSUSE's OpenBuildService
due to glibc's execvp reversing the pointers of 'environ', i.e.,
the output of "env|tac" equals "env env" on that platform.

* tests/misc/printenv.sh: Use 'env env' to work around the behavior
on that platform.
While at it, fix the grep pattern which suppressed all environment
variables starting with an underscore "_" instead of "$_" (and
"$LD_PRELOAD") only.

a5c8cdff03 doc,maint: fix use of "i.e." in documentation and comments
To align with all other places (and correct grammar), change all
upper-case "I.E." to "I.e.".  Furthermore, ensure that "i.e." is
followed by a comma.  Finally, ensure to use a double-space before
"I.e.," at the beginning of a sentence.

The following was used to change all offending uses (apart from
old ChangeLog files):

  $ git grep -liF 'i.e.' \
      | xargs sed -i \
            -e 's/I\.E\./I.e./g' \
            -e 's/\. \(I\.e\.\)/.  \1/g' \
            -e 's/\([Ii]\.e\.\)\( \)/\1,\2/g' \
            -e 's/\([Ii]\.e\.\)$/\1,/g'

Many tests use `program ... && fail=1` to ensure expected

f57bfbb237 build: use the system printf routines in most cases
glibc <= 2.5 would crash when passed invalid long double values,
therefore internal gnulib routines were used, essentially only by od,
to output such invalid values.  Later glibc versions don't crash,
as per https://sourceware.org/bugzilla/show_bug.cgi?id=4586
and subsequently od was adjusted to use the system printf routines
through the use of the ftoastr module with commit v8.7-22-ga71c22f.
Consequently our testing of this feature was moot, and use of
the gnulib printf replacement for printf(1), od(1) and error(3) etc.
was redundant.

* configure.ac (gl_printf_safe): Unset so that we don't check that
"nan" is output for these long double values.
* tests/misc/od-float.sh: Adjust all existing checks to fail if od
exits with failure status (like crashing for example).  Add a new case
for one of the problematic invalid long double values for x86_64.
We only check that od exits successfully at present, which may change
if https://sourceware.org/bugzilla/show_bug.cgi?id=17661 is resolved.

0cf7b1d928 chroot: perform chdir("/") again unless new --skip-chdir is specified
Since commit v8.22-94-g99960ee, chroot(1) skips the chroot(2) syscall
for "/" arguments (and synonyms).  The problem is that it also skips
the following chdir("/") call in that case.  The latter breaks existing
scripts which expect "/" to be the working directory inside the chroot.
While the first part of the change - i.e., skipping chroot("/") - is
okay for consistency with systems where it might succeed for a non-root
user, the second part might be malicious, e.g.

  cd /home/user && chroot '/' bin/foo

In the "best" case, chroot(1) could not execute 'bin/foo' with ENOENT,
but in the worst case, chroot(1) would execute '/home/user/bin/foo' in
the case that exists - instead of '/bin/foo'.

Revert that second part of the patch, i.e., perform the chdir("/)
in the common case again - unless the new --skip-chdir option is
specified.  Restrict this new option to the case of "/" arguments.

* src/chroot.c (SKIP_CHDIR): Add enum.
(long_opts): Add entry for the new --skip-chdir option.
(usage): Add --skip-chdir option, and while at it, move the other
to options into alphabetical order.
(main): Accept the above new option, allowing it only in the case
when NEWROOT is the old "/".
Move down the chdir() call after the if-clause to ensure it is
run in any case - unless --skip-chdir is specified.
Add a 'newroot' variable for the new root directory as it is used
in a couple of places now.
* tests/misc/chroot-fail.sh: Invert the last tests which check the
working directory of the execvp()ed program when a "/"-like
argument was passed: now expect it to be "/" - unless --skip-chdir
is given.
* doc/coreutils.texi (chroot invocation): Document the new option.
Document that chroot(1) usually calls chdir("/") unless the new
--skip-chdir option is specified.  Sort options.
* NEWS (Changes in behavior): Mention the fix.

71e2ea7734 build: support building all tools in a single binary
Add the --enable-single-binary option to the configure file.
When enabled, this option builds a single binary file containing
the selected tools.  Which tool gets executed depends on the value
of argv[0] which can be set implicitly through symlinks to the
single program.

This setup reduces significantly the size of a complete coreutils
install, since code from lib/libcoreutils.a is not duplicated in
every one of the more than 100 binaries.  Runtime overhead is
increased due to more dynamic libraries being loaded, and extra
initialization being performed for all utils.  Also initially
a larger binary is loaded from storage, though this is usually
alleviated due to caching and lazy mmaping of unused blocks,
and in fact the single binary should have better caching
characteristics.

Comparing the size of the individual versus single binary on x86_64:
  $ cd src
  $ size coreutils
  $ size -t $(../build-aux/gen-lists-of-programs.sh --list-progs |
              grep -Ev '(coreutils|libstdbuf)') | tail -n1
     text    data     bss     dec     hex filename
  1097416    5388   88432 1191236  122d44 src/coreutils
  4901010  124964  163768 5189742  4f306e (TOTALS)

Storage requirements are reduced similarly:
  $ cd src
  $ du -h coreutils
  $ du -ch $(../build-aux/gen-lists-of-programs.sh --list-progs |
             grep -Ev '(coreutils|libstdbuf)') | tail -n1
  1.2M    coreutils
  5.3M    total

When installing, the makefile will create either symlinks or
shebangs based on the --enable-single-binary setting, for
each configured tool. In this way, all the tools are still
callable individually, but they are all implemented by the same
"coreutils" binary installed on the same directory.

* src/true.c (main): Add a comment about the possibility
of true returning EXIT_FAILURE due to write failure.

Also remove the iterations for different LC_MESSAGES, as this was only
applied for false(1).  Translations are not honored in the test dir
and so would need separate handling in any case.

5c6cf94ba5 cut: restore special case handling of -f with -d$'\n'
commits v8.20-98-g51ce0bf and v8.20-99-gd302aed changed cut(1)
to process each line independently and thus promptly output
each line without buffering.  As part of those changes we removed
the special handling of --delimiter=$'\n' --fields=... which
could be used to select arbitrary (ranges of) lines, so as to
simplify and optimize the implementation while also matching the
behavior of different cut(1) implementations.

However that GNU behavior was in place for a long time, and
could be useful in certain cases like making a separated list like
`seq 10 | cut -f1- -d$'\n' --output-delimiter=,` although other tools
like head(1) and paste(1) are more suited to this operation.
This patch reinstates that functionality but restricts the
"line behind" buffering behavior to only the -d$'\n' case.

We also fix the following related edge case to be more consistent:

  before> printf "\n" | cut -s -d$'\n' -f1- | wc -l
  2
  before> printf "\n" | cut    -d$'\n' -f1- | wc -l
  1
  after > printf "\n" | cut -s -d$'\n' -f1- | wc -l
  1
  after > printf "\n" | cut    -d$'\n' -f1- | wc -l

ce0c08b52d chroot: with --userspec clear root's supplemental groups
It's dangerous and confusing to leave root's supplemental
groups in place when specifying other users with --userspec.
In the edge case that that is desired one can explicitly
specify --groups.

Also we implicitly set the system defined supplemental groups
for a user.  The existing mechanism where supplemental groups
needed to be explicitly specified is confusing and not general
when the lookup needs to be done within the chroot.

Also we extend the --groups syntax slightly to allow clearing
the set of supplementary groups using --groups=''.

* src/chroot.c (setgroups): On systems without supplemental groups,
clearing then is a noop and so should return success.
(main): Lookup the primary GID with getpwuid() when just a numeric
uid is specified, and also infer the USERNAME from this call,
needed when we're later looking up the supplemental groups for a user.
Support clearing supplemental groups, either implicitly for
unknown users, or explicitly when --groups='' is specified.

f940fece04 ptx: fix whitespace trimming with multiple files
This issue was identified by running the test suite with
http://code.google.com/p/address-sanitizer/
which is included in GCC 4.8 and enabled with -fsanitize=address

This was checked on Fedora 20 with GCC 4.8 as follows:

  $ yum install libasan  # http://bugzilla.redhat.com/991003
  $ rm -f src/ptx.o
  $ make check AM_CFLAGS='-fsanitize=address' SUBDIRS=. VERBOSE=yes
  $ failure identified in tests/test-suite.log

==32178==ABORTING

The initial report and high level analysis were from Jim Meyering...

  "The underlying problem is that swallow_file_in_memory()
  is setting the contents of the global text_buffer for the first file,
  then updating it (clobbering old value) for the second file.
  Yet, some pointers to the initial buffer have been squirreled away
  and later, one of them (keyafter) is presumed to point into
  the new "text_buffer", which it does not.  The subsequent
  SKIP_WHITE_BACKWARDS use backs up "cursor" and goes out of bounds."

* src/ptx.c (text_buffers): Maintain references for the limits of each
buffer corresponding to each file, rather than just the last processed.
(struct OCCURS): Add a member to map back to the corresponding file.
Note normally this could be computed from the "reference" member
rather than needing the extra storage, however this is not possible
when in --references mode.
(find_occurs_in_text): Reference the array rather than a single entry.
(define_all_fields): Likewise.  Also avoid computing the file index
since this is now stored directly.
(main): Update text_buffers[] array rather than a single text_buffer.
* tests/misc/ptx-overrun.sh: Even though this issue is already triggered
with AddressSanitizer, add a new case to demonstrate the whitespace
trimming issue, and to trigger without AddressSanitizer.

initial writes.  It's better to retry direct I/O for each pass
anyway to handle the case where direct I/O is disabled for only
the last portion of a file when the size is not a multiple of
the block size.  Note we don't avoid the sync for the initial
write as it will be small but more importantly could be on a
different part of the disk and so worth doing independently
to ensure the write is not discarded.

e972be3c4b chroot: improve --userspec and --groups look-up
- Support arbitrary numbers in --groups, consistent with
  what is already done for --userspec
- Avoid look-ups entirely for --groups items with a leading '+'
- Support names that are actually numbers in --groups
- Ignore an empty --groups="" option for consistency with --userspec
- Look up both inside and outside the chroot with inside taking
  precedence.  The look-up outside may load required libraries
  to complete the look-up inside the chroot.  This can happen for
  example with a 32 bit chroot on a 64 bit system, where the
  32 bit NSS plugins within the chroot fail to load.

* src/chroot.c (parse_additional_groups): A new function refactored
