fstrim applet is a port from util-linux.
"Trimming" your NAND/eMMC storage will restore the write performance
back to normal after having slow down issues on sequential write and
random write due to usage over time.
Good reading on subject:

While at it, move applet/config/kbuild bits into wall.c.
(This way, it's more visible that applet is suid'ed).

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- '.

Add a helper script that lists all applets that
- do or may require SUID provileges (busybox.cfg.suid)
- do not require SUID provileges (busybox.cfg.nosuid)
Some setups prefer to build two busybox binaries, one that is suid which
contains all applets that do or may require suid privileges, and a
second one for all the rest (which drops suid). To ease splitting these
two binaries, generate a list of CONFIG_ items for the suid binary.

"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.

This makes reading the logic (as well as adding new code) a lot simpler,
and fixes one or two cases that were broken due to incorrect sub-version
tests.

Users were reporting getting errors like
"ls: error while loading shared libraries: libc.so.6: ELF load command past end of file"
while rpm was unpacking glibc tarball.

This makes unzip to FAT filesystems not exit with error.
This is similar to how the "normal" unzip works.

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.
