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.

kill: add '--' option to separate options from arguments
Using a negative pid to send TERM to a process group results in an
obscure error:
$ ./busybox kill -12345
kill: bad signal name '12345'
This is intended. Manpage says:
ARGUMENTS
pid Each pid can be one of four things:
...
-n where n is larger than 1. All processes in process group
n are signaled. When an argument of the form '-n' is
given, and it is meant to denote a process group, either
a signal must be specified first, or the argument must be
preceded by a '--' option, otherwise it will be taken as
the signal to send.
However, we did not support "--". Add this capability to BusyBox.

hush: implement -d DELIM option for 'read'
The POSIX standard only requires the 'read' builtin to handle '-r':
http://pubs.opengroup.org/onlinepubs/

However, Bash introduced the option '-d <DELIM>' to override IFS for
just one invocation, and it is quite useful.
We already support this in ash, let's add it to hush, too.

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.

setconsole: much better help text
Was:
Usage: setconsole [-r] [DEVICE]
Redirect system console output to DEVICE (default: /dev/tty)
-r Reset output to /dev/console
Now:
Usage: setconsole [-r] [DEVICE]
Make writes to /dev/console appear on DEVICE (default: /dev/tty).
Does not redirect kernel log output or reads from /dev/console.
-r Reset: writes to /dev/console go to kernel log tty(s)
