Address a couple errors identified by ORCA/C 2.2.0 B2.
...
One of these concerned socket-related structures that aren't really used in hush. The other was a reliance on a GCC-specific feature (arithmetic on void pointers); this code is actually used in hush, although I'm not sure if the error was causing any real problems.

Merge with BusyBox 1.24.0.
...
There's really only one bug fix in here that should be significant for GNO hush. The other changes should be inconsequential, AFAIK.

unit-tests: remove unnecesary field from struct bbunit_listelem

In the initial submission struct bbunit_listelem was manipulated by
custom list functions implemented in bbunit.c. Since the tests are now
added to the list by llist_add_to_end(), which allocates the llist_t
objects behind the scenes, there's no need for the *next field.

*: Switch to POSIX utmpx API

UTMP is SVID legacy, UTMPX is mandated by POSIX.
Glibc and uClibc have identical layout of UTMP and UTMPX, both of these
libc treat _PATH_UTMPX as _PATH_UTMP so from a user-perspective nothing
changes except the names of the API entrypoints.

Fix sigaddset/sigdelset/sigismember macros to support signals above 16.
...
The versions in the GNO 2.0.6 headers are broken--they don't account for int being 16-bit, so they cut off the higher signals.

Merge with BusyBox 1.23.0.

The only substantive change is about when simple line input mode is used.
I also bumped the version number and included a GNO-version-specific component.

libarchive: add capability to unpack to mem.buffer
...
The performance and number of processes for a "depmod -a" with gzipped
modules was abysmal. This patch adds a code path without fork,
benefiting all users of xmalloc_open_zipped_read_close.
"modinfo radeon.ko.gz", a single-file reader, got 30% faster.
"depmod -a", which used to fork over 800 times, got 20% faster.
Heavily based on a patch by Lauri Kasanen <curaga@operamail.com>

Work around an ORCA/C preprocessor bug that was causing shell conditionals not to work properly.
...
The bug is that an #if condition may be mis-evaluated if it immediately follows a use of a function-like macro. I also modified a couple other places that could possibly trigger the bug (including a possibly more reliable fix for the instance of this problem I worked around earlier in include/xatonum.h).

Implement "close-on-exec" functionality for GNO.
...
We do this by maintaining a mask (for each pid) giving the fds to be closed on exec. We wrap functions that close fds so that their close-on-exec bits can be cleared at that point.
This implementation may close the fds even if the execve operation ultimately fails.

libbb: use ARG_MAX for bb_arg_max() only if it's 60k+
...
Sometimes ARG_MAX is small (like 32k) yet sysconf(_SC_ARG_MAX)
is big, and people prefer using the bigger value.
OTOH, with sufficiently large ARG_MAX, further wins from
sysconf(_SC_ARG_MAX) being bigger are exponentially smaller:
you can see 4 times fewer fork+execs when you run find, but
when each execed process already takes a thousand parameters
it's likely execution time is dominated by what that process
does with each parameter.
Thus, with this change ARG_MAX is used if it's sufficiently big,
otherwise sysconf(_SC_ARG_MAX) is used.

Fix our handling of process groups for job control, working around a couple GNO bugs.
...
*Most significantly, we avoid using setpgid(), because it doesn't work and in fact corrupts the kernel's process group table.
*Also, work around tctpgrp() returning garbage instead of 0 on success.
This adds an implementation of tcsetpgrp that works by reading the process tables to find a process in the appropriate group. This isn't used for the main job control operations, though, since it might be relatively slow.
At this point, basic job control seems to work.

Fix to assign valid pgrps to child processes. On GNO, we can't just use the pid as a pgrp; we must call tcnewpgrp instead.

Fixes for environment variable handling on GNO:
...
* Push/pop environment to make sure it is isolated from our parents and children.
* Make all environment vars (and shell vars) case-insensitive, consistent with GNO's internal handling of environment vars.
* Wrap putenv and unsetenv to make sure they are called with lower-case variable names, which is necessary to maintain consistency between the environ array and the kernel's internal representation of variables.
