0d1eaf407c i2c-tools: don't include linux/i2c-dev.h
Installing headers from upstream i2c-tools makes it impossible to
build the busybox version due to redefined symbols. This is caused by
the fact that linux/i2c-dev.h from i2c-tools overwrites the one from
linux uapi and defines symbols already defined by linux' linux/i2c.h.

Drop this include and simply re-implement the relevant defines from
linux/i2c-dev.h in miscutils/i2c-tools.c.

Tested by building on systems with and without i2c-tools headers.

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.

31c765081d watchdog: stop watchdog first on startup
Some watchdog implementations may do things other than issue
a reboot on a watchdog timeout.  In this case, there's the
possibility of restarting this program from the state of
the watchdog device not being properly stopped (done by writing
a 'V' and closing the device).  Since it wasn't stopped, the
driver may not be able to restart the watchdog when this program
reopens it and starts pinging it.

To fix this, the code will always first issue the stop when it
starts up.
