d3539be8f2 Remove stime() function calls
stime() has been deprecated in glibc 2.31 and replaced with
clock_settime(). Let's replace the stime() function calls with
clock_settime() in preperation.

6937487be7 libbb: reduce the overhead of single parameter bb_error_msg() calls
Back in 2007, commit 0c97c9d437 ("'simple' error message functions by
Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower
overhead call to bb_perror_msg() when only a string was being printed
with no parameters. This saves space for some CPU architectures because
it avoids the overhead of a call to a variadic function. However there
has never been a simple version of bb_error_msg(), and since 2007 many
new calls to bb_perror_msg() have been added that only take a single
parameter and so could have been using bb_simple_perror_message().

This changeset introduces 'simple' versions of bb_info_msg(),
bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and
bb_herror_msg_and_die(), and replaces all calls that only take a
single parameter, or use something like ("%s", arg), with calls to the
corresponding 'simple' version.

Since it is likely that single parameter calls to the variadic functions
may be accidentally reintroduced in the future a new debugging config
option WARN_SIMPLE_MSG has been introduced. This uses some macro magic
which will cause any such calls to generate a warning, but this is
turned off by default to avoid use of the unpleasant macros in normal
circumstances.

This is a large changeset due to the number of calls that have been
replaced. The only files that contain changes other than simple
substitution of function calls are libbb.h, libbb/herror_msg.c,
libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c,
networking/udhcp/common.h and util-linux/mdev.c additonal macros have
been added for logging so that single parameter and multiple parameter
logging variants exist.

The amount of space saved varies considerably by architecture, and was
found to be as follows (for 'defconfig' using GCC 7.4):

Arm:     -92 bytes
MIPS:    -52 bytes
PPC:   -1836 bytes
x86_64: -938 bytes

Note that for the MIPS architecture only an exception had to be made
disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h)
because it made these files larger on MIPS.

498cec202a mdev: add support to run as daemon
Adds the -d option to run mdev in daemon mode handling hotplug events
from the kernel like udev. If the system generates many hotplug events
this mode of operation will consume less resources than registering
mdev as hotplug helper or using the uevent applet.

71df2d3589 hush: allow hush to run embedded scripts
Embedded scripts require a shell to be present in the BusyBox

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.

3778898f97 Treat custom and applet scripts as applets
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.

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.
