036585a911 getopt32: remove applet_long_options
FEATURE_GETOPT_LONG made dependent on LONG_OPTS.

The folloving options are removed, now LONG_OPTS enables long options
for affected applets:
FEATURE_ENV_LONG_OPTIONS	FEATURE_EXPAND_LONG_OPTIONS
FEATURE_UNEXPAND_LONG_OPTIONS	FEATURE_MKDIR_LONG_OPTIONS
FEATURE_MV_LONG_OPTIONS		FEATURE_RMDIR_LONG_OPTIONS
FEATURE_ADDGROUP_LONG_OPTIONS	FEATURE_ADDUSER_LONG_OPTIONS
FEATURE_HWCLOCK_LONG_OPTIONS	FEATURE_NSENTER_LONG_OPTS
FEATURE_CHCON_LONG_OPTIONS	FEATURE_RUNCON_LONG_OPTIONS

They either had a small number of long options, or their long options are
essential.

Example: upstream addgroup and adduser have ONLY longopts,
we should probably go further and get rid
of non-standard short options.

To this end, make addgroup and adduser "select LONG_OPTS".
We had this breakage caused by us even in our own package!
	#if ENABLE_LONG_OPTS || !ENABLE_ADDGROUP
                /* We try to use --gid, not -g, because "standard" addgroup
                 * has no short option -g, it has only long --gid.
                 */
                argv[1] = (char*)"--gid";
	#else
                /* Breaks if system in fact does NOT use busybox addgroup */
                argv[1] = (char*)"-g";
	#endif

xargs: its lone longopt no longer depends on DESKTOP, only on LONG_OPTS.

hwclock TODO: get rid of incompatible -t, -l aliases to --systz, --localtime

Shorten help texts by omitting long option when short opt alternative exists.

Reduction of size comes from the fact that store of an immediate
(an address of longopts) to a fixed address (global variable)
is a longer insn than pushing that immediate or passing it in a register.
This effect is CPU-agnostic.

5c527dc57e make 17 state-changing execing applets (ex: "nice PROG ARGS") noexec
The applets with "<applet> [opts] PROG ARGS" API very quickly exec
another program, noexec is okay for them:

 chpst/envdir/envuidgid/softlimit/setuidgid
 chroot
 chrt
 ionice
 nice
 nohup
 setarch/linux32/linux64
 taskset
 cttyhack

"reset" and "sulogin" applets don't have this form, but also exec
another program at once, thus made noexec too.

    I see, you're right.  Thanks, Gerrit.

    This patch hard-codes the 3,4-argument cases in the way required by
    POSIX.

a165603d24 od_bloaty: fix floating point output
Currently od_bloaty does this:

   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -f
   od: invalid character 'F' in type string 'fF'
   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -t fD
   od: invalid character 'D' in type string 'fD'
   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -t f
   0000000
   0000010

The first two occur because the alphabetic length specifier isn't being
properly skipped.  The third is due to the empty length specifier being
treated as alphabetic so we fall off the end of the FDL_sizeof array with
undetermined consequences.  Coreutils defaults to printing a double in
this case.

With this patch the output is:

   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -f
   0000000   0.0000000e+00   0.0000000e+00
   0000010
   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -t fD
   0000000   0.000000000000000e+00
   0000010
   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -t f
   0000000   0.000000000000000e+00
   0000010

I guess nobody uses BusyBox od to print floating point numbers.

513a2457b6 printf: fix format string sanity check
One of the tests for printf checks for an invalid bare '%' in the
format string:

   $ busybox printf '%' a b c
   printf: %: invalid format

On x86_64 a slightly different test doesn't work correctly:

   $ busybox printf '%' d e f
   printf: invalid number 'd'
   printf: invalid number 'e'
   printf: invalid number 'f'

On other platforms the test fails randomly depending on how the
arguments are laid out in memory.

There are two places in the code where strchr is used to determine if
a character in the format string is valid.  However, strchr also returns
a valid pointer if the character being searched for is the null terminator
thus causing the code to incorrectly suppose that a valid character has
been found.

Add explicit checks for the null terminator.

9de9c871bf shuf: fix random line selection. Closes 9971
"""
For example, given input file:

    foo
    bar
    baz

after shuffling the input file, foo will never end up back on the first line.
This came to light when I ran into a use-case where someone was selecting
a random line from a file using shuf | head -n 1, and the results on busybox
were showing a statistical anomaly (as in, the first line would never ever
be picked) vs the same process running on environments that had gnu coreutils
installed.

On line https://git.busybox.net/busybox/tree/coreutils/shuf.c#n56 it uses
r %= i, which will result in 0 <= r < i, while the algorithm specifies
0 <= r <= i.

color support was not. This patch ensures long options are
