3d9c649158 ls: don't output any colors with TERM=dumb
The TERM variable is usually set to "dumb" to indicate that the terminal
does not support any ANSI escape sequences. Presently, ls does not honor
this variable and outputs colors anyhow which results in unreadable
output, unless the user explicitly disables colors using `ls
--color=never`. The rational behind this change is that ls should "just
work" by default, even on dumb terminals.

For this reason, this patch adds a check which additionally consults the
TERM variable before printing any colors. This is analogous to the
existing check for ensuring that standard output is a tty. As such,
colors can still be forced with `--color=force`, even if TERM is set to
dumb.

79c92dbd70 touch: switch to using utimensat() and futimens()
This patch changes the functions used to update timestamps in touch.

Before, utimes() and lutimes() were used, which had certain
disadvantages.
They are unable to handle nanosecond timestamps, and implementations of
certain features like -a and -m require running stat() in a loop.

Almost all implementations of utimes() and lutimes() are wrappers for
utimensat(), this is the case for glibc, ulibc and musl libc.

7ec254467c touch: remove unneeded GETOPT32 defines
Long options handling (getopt32 vs getopt32long) is done in libbb.h, no need to
care here of the same logic. This cleans the code a bit.

Also, --no-create was grouped as a SUSv3 option, where as the short -c was not.
Even if it is part of SUS, leave it out as was the short option.

v2: Fix for disabled ENABLE_LONG_OPTS. getopt32long does not like
  IF_FEATURE_xxx() style conditionals... :/

e880c9c100 echo: do not assume that free() leaves errno unmodified
musl libc's mallocng free() may modify errno if kernel does not support
MADV_FREE which causes echo to echo with error when it shouldn't.

Future versions of POSIX[1] will require that free() leaves errno
unmodified but til then, do not rely free() implementation.

Should fix downstream issues:

c849e72c0b nl: ensure '-b n' option displays file content
The command 'nl -b n' should output no line numbers, just some
spaces as a placeholder followed by the actual file content.

Add tests for line numbering by cat and nl.  The correct results
were obtained from coreutils.

Prior to the patch, both -f and --first-only are in all cases either
no-op or ignored.
Without --tabs, --first-only is the default so specifying it is a no-op.
With --tabs, --all is implied, and --first-only is intended to reset this.

af6bc54fde chgrp: correct the usage for non-desktop chgrp calls
When IF_DESKTOP is not defined, chown and chgrp only takes option -R -h,
However the usage output of chgrp is wrong:

	$ ./busybox.nosuid chown
	Usage: chown [-Rh]... USER[:[GRP]] FILE...

	$ ./busybox.nosuid chgrp
	Usage: chgrp [-RhLHP]... GROUP FILE...

	$ ./busybox.nosuid chgrp -H group dummy
	chgrp: invalid option -- 'H'
	Usage: chgrp [-RhLHP]... GROUP FILE...

The chgrp is now a wrapper of chown, so the recognized options shall be the same.
This is introduced by 34425389e0

I would expect the correct behavior shall be the same as chown.
So suggest the below patch, the behavior shall be:

	$ ./busybox.nosuid chgrp
	Usage: chgrp [-Rh]... GROUP FILE...

b7b7452f29 date: Use 64 prefix syscall if we have to
Some 32-bit architectures no longer have the 32-bit time_t syscalls.
Instead they have suffixed syscalls that returns a 64-bit time_t. If
the architecture doesn't have the non-suffixed syscall and is using a
64-bit time_t let's use the suffixed syscall instead.

This fixes build issues when building for RISC-V 32-bit with 5.1+ kernel
headers.

If an architecture only supports the suffixed syscalls, but is still
using a 32-bit time_t fall back to the libc call.

6937487be7 libbb: reduce the overhead of single parameter bb_error_msg() calls
Back in 2007, commit 0c97c9d437 ("'simple' error message functions by
Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower
overhead call to bb_perror_msg() when only a string was being printed
with no parameters. This saves space for some CPU architectures because
it avoids the overhead of a call to a variadic function. However there
has never been a simple version of bb_error_msg(), and since 2007 many
new calls to bb_perror_msg() have been added that only take a single
parameter and so could have been using bb_simple_perror_message().

This changeset introduces 'simple' versions of bb_info_msg(),
bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and
bb_herror_msg_and_die(), and replaces all calls that only take a
single parameter, or use something like ("%s", arg), with calls to the
corresponding 'simple' version.

Since it is likely that single parameter calls to the variadic functions
may be accidentally reintroduced in the future a new debugging config
option WARN_SIMPLE_MSG has been introduced. This uses some macro magic
which will cause any such calls to generate a warning, but this is
turned off by default to avoid use of the unpleasant macros in normal
circumstances.

This is a large changeset due to the number of calls that have been
replaced. The only files that contain changes other than simple
substitution of function calls are libbb.h, libbb/herror_msg.c,
libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c,
networking/udhcp/common.h and util-linux/mdev.c additonal macros have
been added for logging so that single parameter and multiple parameter
logging variants exist.

The amount of space saved varies considerably by architecture, and was
found to be as follows (for 'defconfig' using GCC 7.4):

Arm:     -92 bytes
MIPS:    -52 bytes
PPC:   -1836 bytes
x86_64: -938 bytes

Note that for the MIPS architecture only an exception had to be made
disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h)
because it made these files larger on MIPS.
