d077565bb2 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.

d840c5d139 libbb: add a function to make a copy of a region of memory
Introduce a library routine to package the idiom:

    p = xmalloc(b, n);
    memcpy(p, b, n);

and use it where possible.  The example in traceroute used xzalloc
but it didn't need to.

86a7f18f21 *: 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.

b4c11c1397 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>

04c1417602 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.

bf0f2c7aa6 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.

f92f1d0181 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.

79c618c411 Refactor catv. Move visible() from stty to libbb.
Fixes the following TODO:

  stty's visible() function and catv's guts are identical. Merge them into
  an appropriate libbb function.

Also makes catv behave exactly like coreutils' cat -v e.g. it'll print 'M-^I'
instead of 'M-   '.

"losetup -d" was not complaining that LOOPDEV is missing.
"losetup -a" was listing only up to /dev/loop9.
"losetup -f" looped forever if llop0 was taken, and never tried
anything after /dev/loop9.
"-o" with other options (say, -r) had no effect.

02112d8ae3 unzip: ignore chmod errors
This makes unzip to FAT filesystems not exit with error.
This is similar to how the "normal" unzip works.

576b1d3c41 sendmail: use host rather than NIS domain name for HELO
According to RFC 5321 the argument to HELO "contains the fully-qualified
domain name of the SMTP client" or its IP address if no FQDN is available.
BusyBox sendmail uses the NIS domain name instead which, in many cases,
is likely to be the default "(none)". [vda: yes, I checked my machine
and its uts.domainname was indeed "(none)"]

Using the host name is more likely to satisfy the intent of the RFC while
allowing the otherwise unused safe_getdomainname function to be removed.
