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.

64ed5f0d3c uname: make OS name configurable
A mailing list thread in September 2013 discussed changing the string
returned by the non-POSIX 'uname -o' option.  Nothing ever came of this
because there was no agreement as to what the string should be.

Make the string configurable so that people can decide for themselves.

67b23e6043 getopt_ulflags -> getopt32.
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

for -p to match normal uname behavior (at a cost of 30-40 bytes).

cbe31dace5 It turns out that DODMALLOC was broken when I reorganized busybox.h
header file usage before the 0.49 release.  To fix it, I had to move
the '#include "busybox.h"' to the end of the list of #include files.

67991cf824 This patch, put together by Manuel Novoa III, is a merge of work
done by Evin Robertson (bug#1105) and work from Manuel to make
usage messages occupy less space and simplify how usage messages
are displayed.

ed3ef50c23 Fix header file usage -- there were many unnecessary header files included in
busybox.h which slowed compiles.  I left only what was needed and then fixed up
all the apps to include their own header files.  I also fixed naming for pwd.h
and grp.h functions.  Tested to compile and run with libc5, glibc, and uClibc.
