50a37459ff watchdog: make open-write-close-open functionality a config knob
The behaviour introduced by commit 31c765081d ("watchdog: stop
watchdog first on startup") causes warnings in the kernel log when the
nowayout feature is enabled:

[   16.212184] watchdog: watchdog0: nowayout prevents watchdog being stopped!
[   16.212196] watchdog: watchdog0: watchdog did not stop!

The latter may also appear by itself in case the watchdog is of the
type that cannot be stopped once started (e.g. the common
always-running gpio_wdt kind).

These warnings can be somewhat ominous and distracting, so allow
configuring whether to use this open-write-close-open sequence rather
than just open. Also saves a bit of .text when disabled:

Make it default n:

- It's a workaround for one specific type of watchdog (and
  that seems to be a defect in the kernel driver)
- Even when not enabled in busybox config, it can easily be
  implemented outside busybox
- Code size
- Commit 31c765081d should be considered a regression for all the
  boards that now end up with KERN_CRIT warnings in dmesg.
- The author of that commit said "This use case is evidently rare, so
  if it is indeed causing problems for other people I'd OK then I
  understand whatever needs to be done." in the v1 thread.

051665ef69 crontab: Fix -e with editors saving using renaming strategy
Some editors (like vim) use renaming strategy to save file. That means
they save a file to some random name and then rename it to final
location. The advantage is that such save is atomic.

However, crontab -e holds open fd to the temporary file, meaning it
never sees the changes. The temporary file needs to be re-opened after
the editor terminates for the changes to properly save.

Fixes #12491

981b2eff81 mim: run scripts from a specification file
mim runs scripts from a specification file which can be thought
of as an extremely limited Makefile. Neither make variables nor
dependencies are supported. By default the file 'Mimfile' is read.
An example:

   hello:
      echo hello $1

   clean:
      rm -rf *

The command 'mim' or 'mim hello' will echo 'hello'. Unlike 'make'
arguments after the first are available to the script; they don't
specify additional targets.

mim isn't enabled by default.  Enabling it increases the size of the
binary by about 500 bytes.

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.

253c4e787a Optionally re-introduce bb_info_msg()
Between Busybox 1.24.2 and 1.25.0 the bb_info_msg() function was
eliminated and calls to it changed to be bb_error_msg(). The downside of
this is that daemons now log all messages to syslog at the LOG_ERR level
which makes it hard to filter errors from informational messages.

This change optionally re-introduces bb_info_msg(), controlled by a new
option FEATURE_SYSLOG_INFO, restores all the calls to bb_info_msg() that
were removed (only in applets that set logmode to LOGMODE_SYSLOG or
LOGMODE_BOTH), and also changes informational messages in ifplugd and
ntpd.

The code size change of this is as follows (using 'defconfig' on x86_64
with gcc 7.3.0-27ubuntu1~18.04)

3c6f3336e1 man: don't skip default path which appears in config file
If the MANPATH environment variable isn't set a provisional default
path of /usr/man is placed in man_path_list.  This is only used if a
configuration file doesn't contain an alternative path.

If a configuration file lists the default path first:

   MANPATH /usr/man:/usr/share/man

add_MANPATH() sees that the default entry is already present and skips
it.  As a result man_path_list only contains the second and subsequent
components of the configured MANPATH.

In such cases the path should not be skipped.
