ccb8e4bc4f fsck: fix incorrect handling of child exit
In commit

  c4fb8c6a - fsck: do not use statics

not only statics were changed but also a couple of
statics-unrelated changes were made.

This included the handling of the child termination status
as follows:

    - if (WIFEXITED(status))
    -   status = WEXITSTATUS(status);
    - else if (WIFSIGNALED(status)) {
    + status = WEXITSTATUS(status);
    + if (WIFSIGNALED(status)) {

This is wrong, should have used a different variable to hold exit code.

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.

296381ff4f applets/install: don't try to install nothing
Commit 952d5a6024 (applets/install: accept more than one install
option) changed the way we handle install options: before that commit, a
missing install type would mean to install nothing; after, we would
iterate over options, so we would never notice there was a mising
option.

Fix that by introducing an explicit --none option to specify to install
nothing.

d5f5045b43 ash: expand: Fix buffer overflow in expandmeta
Upstream commit:

    Date: Sun, 25 Mar 2018 16:38:00 +0800
    expand: Fix buffer overflow in expandmeta

    The native version of expandmeta allocates a buffer that may be
    overrun for two reasons.  First of all the size is 1 byte too small
    but this is normally hidden because the minimum size is rounded
    up to 2048 bytes.  Secondly, if the directory level is deep enough,
    any buffer can be overrun.

    This patch fixes both problems by calling realloc when necessary.
