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.

415cc42b6a Reorder modutils config options & fix yet more dependency
- modprobe can indirectly benefit from FEATURE_2_4_MODULES and
  FEATURE_INSMOD_TRY_MAP options.
- The position of config FEATURE_INSMOD_TRY_MMAP prevented some other
  config options from indenting under FEATURE_2_4_MODULES. Reorder to
  fix this.
- FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED is now moved to
  Config.src under "Common options" section. (I wished to edit this
  config so that it also work with "big" modutils, but it's not done at
  the moment. Sorry.)

  operation. (And it no longer need to die if such modules directory
  doesn't exist.)
- Configs DEFAULT_MODULES_DIR and DEFAULT_DEPMOD_FILE no longer depend
  on MODPROBE_SMALL as the latter may not enable depmod or modprobe
  that requires these configs.
- Clarify DEFAULT_DEPMOD_FILE's description regarding the ".bb" name
  suffix.

Allow module options on command line to be disabled on "big" modutils.

Config FEATURE_MODPROBE_SMALL_OPTIONS_ON_CMDLINE is renamed to
FEATURE_CMDLINE_MODULE_OPTIONS and no longer depends on !MODPROBE_SMALL

(I'm not sure if disabling this is useful on "big" modutils, but at
least the macro can serve as a marker and ensure both implementations
of same feature have consistent behavior.)

065e988e7a modutils: fix config options dependency
module.aliases and module.symbols files have no use in modprobe-small
implementation. So FEATURE_MODUTILS_ALIAS and FEATURE_MODUTILS_SYMBOLS
will depend on !MODPROBE_SMALL.

The try_to_mmap_module() function is not called in modprobe-small.c,
so I will let FEATURE_INSMOD_TRY_MMAP depend on !MODPROBE_SMALL for
now.

80172e4622 modprobe-small: optimizations for single applet build
(I'm requesting for a review first because I fear such an aggressive
change could lead to bugs. While I observe the sizes have reduced, I
haven't test the functionality of each applet after that. So please
test before merging.)

Aggressively cut off unneeded code when the relevant applets are not
built.

Correct dependencies of FEATURE_MODPROBE_SMALL_OPTIONS_ON_CMDLINE and
FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED.

Don't bother with the '-r' option check if only rmmod is built (assume
true then), or when neither rmmod or mobprobe is built (assume false
then).

Size comparison before and after the change (single applet
configuration):

9c083f599a modutils: remove special handling of uClibc
Commit 3a45b87ac3 (modutils: support finit_module syscall) introduced
macro finit_module. But it is not defined for uClibc.

The compilation for busybox fails for MIPS with:
With uClibc, we get following build errors:

  modutils/lib.a(modutils.o): In function `bb_init_module':
  modutils.c:(.text.bb_init_module+0x94): undefined reference to `finit_module'
  modutils.c:(.text.bb_init_module+0xa0): undefined reference to `finit_module'

We can just use syscall() without any need for the
uClibc wrappers.

Newer versions of uClibc-ng (>1.0.20) will remove the
module syscall wrappers.

3a45b87ac3 modutils: support finit_module syscall
On some systems like Chromium OS, loading modules from non-verified
filesystems is denied.  Only finit_module is allowed because an open
fd is passed which can be checked against a verified location.

Change the module loading code to first attempt finit_module and if
that fails for whatever reason, fall back to the existing logic.

On x86_64, this adds ~80 bytes to modutils/modutils.o and ~68 bytes
to modutils/modprobe-small.o.
