Embedded scripts require a shell to be present in the BusyBox
binary. Allow either ash or hush to be used for this purpose.
If both are enabled ash takes precedence.
The size of the binary is unchanged in the default configuration:
both ash and hush are present but support for embedded scripts
isn't compiled into hush.

BusyBox has support for embedded shell scripts. Two types can be
distinguished: custom scripts and scripts implementing applets.
Custom scripts should be placed in the 'embed' directory at build
time. They are given a default applet configuration and appear
as applets to the user but no further configuration is possible.
Applet scripts are integrated with the BusyBox build system and
are intended to be used to ship standard applets that just happen
to be implemented as scripts. They can be configured at build time
and appear just like native applets.
Such scripts should be placed in the 'applets_sh' directory. A stub
C program should be written to provide the usual applet configuration
details and placed in a suitable subsystem directory. It may be
helpful to have a configuration option to enable any dependencies the
script requires: see the 'nologin' applet for an example.

Kconfig-language.txt was deleted in commit 4fa499a17b52b back in 2006.
Move to docs/ as suggested by Xabier Oneca:
http://lists.busybox.net/pipermail/busybox/2014-May/080914.html
Also update references to it everywhere.

-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:

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 036585a911a5f, the usage message erroneously
claimed that the long option was indeed called --net; after that commit
long options are not listed at all.

In practice, "wget http://host.com/" always uses port 80.
People explicitly set non-standard ports via options or parameters
("telnet 1.2.3.4 567" or "telnet 1.2.3.4 ftp") instead of modifying
/etc/services.

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.

"-c, --no-canonicalize: Do not canonicalize paths."
As busybox doesn't canonicalize paths in the first place it is safe to ignore
this option.
