libiproute: rename invarg(a,b) to invarg_1_to_2(a,b)
...
invarg(a,b) - "invalid argument", but how a and b enter the message?
invarg_1_to_2(a,b) is somewhat easier to read: "invalid argument 'a' to 'b'"
Audit of usage revealed a number of bad uses, with too long messages.

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.

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>

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.

Rename INIT_LAST to INIT_FUNC to avoid confusion
...
We don't have an INIT_FIRST, so let's rename INIT_LAST to INIT_FUNC
to imply that the function is called at program start-up.
Also: the priority argument for __attribute__((constructor)) isn't
used, so let's remove it.

find: use sysconf(_SC_ARG_MAX) to determine the command-line size limit
...
The find utility uses a hardcoded value of 32 * 1024 as the limit of
the command-line length when calling 'find -exec ... {} +'. This results
in over 4 times more execve() calls than in coreutils' find.
This patch uses the limit defined in system headers.
