build system: drop PLATFORM_LINUX
...
PLATFORM_LINUX is a hidden configuration option which is disabled by
default and enabled at over a hundred locations for features that are
deemed to be Linux specific.
The only effect of PLATFORM_LINUX is to control compilation of
libbb/match_fstype.c. This file is only needed by mount and umount.
Remove all references to PLATFORM_LINUX and compile match_fstype.c
if mount or umount is enabled.

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

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.

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)

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.
