254e47372f nsenter: fix parsing of -t, -S and -G options 
-t, -S and -G each take mandatory integer arguments.   getopt32long()'s
option string syntax for this type of argument is 'c:+', however nsenter's
opt_str uses 'c+', which specifies two options 'c' and '+' which do not
take arguments.   This means that giving a target PID causes nsenter to
exit and print the usage string:

  # nsenter -t1 sh
  nsenter: unrecognized option: 1
  BusyBox v1.27.2 (2017-12-12 10:41:50 GMT) multi-call binary.
  ...

The long form options are also broken:

  # nsenter --setuid=1000 --setgid=1000 sh
  BusyBox v1.29.0.git (2018-05-04 13:56:49 UTC) multi-call binary.
  ...

`nsenter --target=<pid> sh` parses correctly and appears to work, but
<pid> is ignored and set to 0.   This doesn't raise an error unless one
of the namespace arguments is also given:

  # ./busybox_unstripped nsenter --target=42 sh
  # exit

  # ./busybox_unstripped nsenter -n --target=42 sh
  BusyBox v1.29.0.git (2018-05-04 13:56:49 UTC) multi-call binary.
  ...

This has caused problems in a couple of places:

40394cb1c9 nsenter: Rename --network option to --net 
In nsenter from util-linux, the long version of the -n option is
--net=<path>.   BusyBox's version expects --network=<path>, so scripts
and examples written for util-linux's version cause BusyBox's version
to exit with the usage message.

Confusingly, until commit 036585a911, the usage message erroneously
claimed that the long option was indeed called --net; after that commit
long options are not listed at all.

e411cd071a volume_id: add LittleFS detection 
Add support for LittleFS to blkid. Not included if FEATURE_BLKID_TYPE
is not selected (neither UUID nor label).

LittleFS is a small fail-safe filesystem designed for embedded
systems. It has strong copy-on-write guarantees and storage on disk
is always kept in a valid state. It also provides a form of dynamic
wear levelling for systems that can not fit a full flash translation
layer. (https://github.com/geky/littlefs)

ARM has introduced it in its Mbed OS 5.7, so it starts to gain focus.
(https://os.mbed.com/blog/entry/littlefs-high-integrity-embedded-fs/)
