There is a call to swapoff in the shutdown sequence, so call "swapon -a"
on startup. As stated in the swapon man page,
All devices marked as "swap" in /etc/fstab are made available, except
for those with the "noauto" option. Devices that are already being
used as swap are silently skipped.
So even if the system has some init script to start/stop swap (e.g. from
a rootfs ovelay) calling swapon/swapoff would be harmless.

Commit b4fc5a180c (package/busybox: support spaces in module aliases in
mdev) changed the mdev coldplugging to handle sysfs path elements and
modalias values containing spaces. This unfortunately doesn't work as was
recently reported:
http://lists.busybox.net/pipermail/buildroot/2018-May/220903.html
The problem is that sort -z also expects the fields of the input files to be
zero terminated, which is not the case for modalias sysfs entries.
So drop the -z option to sort. Spaces in modalias entries could be handled
with the xargs -d '\n' option, but that is unfortunately not supported by
the busybox applet. Instead, use tr to convert newlines to zeros so we can
use xargs -0.

Some applications, e.g. bashs process subsitution feature, rely on the
convention of `/dev/fd` being a symbolic link to `/proc/self/fd`.
This symbolic link and his companions `/dev/std*` are created by (e)udev [1],
but not by mdev, resulting in the following error when using the following
expression:
```
bash: /dev/fd/62: No such file or directory
```
For the sake of simplicity, lets fix this by creating the symlinks in inittab.
It is only really needed if eudev isn't used, but it doesn't really hurt to
create them even if eudev will recreate them afterwards.
Note, that we do not create the symlink `/dev/core` as `/proc/kcore` is
not available on all platforms, e.g. ARM, and the feature is not much
appreciated [2].

Currently there is only logic to enable PAM when linux-pam is selected.
However, busybox will fail to build with PAM enabled if the linux-pam
package has not been built before. So we should forcibly disable PAM in
busybox in that case.
Normally this is not an issue since our default busybox config doesn't
have PAM enabled. However, if you enable linux-pam, then save the
busybox config to a custom configuration file, then disable linux-pam
again, and then do a "make clean; make", the build will fail. A more
practical situation where this can occur is when the same custom
busybox config is used in a Buildroot config with and without
linux-pam.

The current busybox.mk explicitly removes S01logging if CONFIG_SYSLOGD
is disabled in the Busybox configuration. However:
- This causes the removal of the S01logging script potentially
installed by another package (currently syslog-ng, rsyslog and
sysklogd can all install a S01logging script).
- We generally don't try to clean-up stuff that we may have installed

FEATURE_CLEAN_UP is a configuration feature to get busybox to explicitly
call free() on dynamic allocated memory just before exiting so memory leak
detectors like valgrind don't get confused. Upstream explicitly recommends
to NOT enable this option:
config FEATURE_CLEAN_UP
bool "Clean up all memory before exiting (usually not needed)"
default n
help
As a size optimization, busybox normally exits without explicitly
freeing dynamically allocated memory or closing files. This saves
space since the OS will clean up for us, but it can confuse debuggers
like valgrind, which report tons of memory and resource leaks.
Don't enable this unless you have a really good reason to clean
things up manually.
Having this option enabled adds a bit of bloat, but more significantly these
cleanup code paths don't get tested very often so some times get out of sync
with the allocation code which can lead to crashes (or security issues from
double frees), so it is safer to disable the option.
For people wanting to debug memory leak issues with busybox, the option can
still be enabled with a configuration fragment (or a custom config).
The size difference isn't huge (br-arm-full-static):

Removing clear and reset from the busybox config when the ncurses tools
are enabled is not really needed.
Since commit 802bff9c42, the busybox install will not overwrite
existing programs. Therefore, the tools will be installed correctly
regardless of the order of the build:
- if busybox is built first, the clear and reset apps are installed,
but they will be overwritten by ncurses;
- if ncurses is built first, it will install the clear and reset apps,
and busybox will no longer install them.
We prefer not to modify the busybox configuration when not strictly
necessary, because it is surprising for the user that his configuration
is not applied. Clearly, it's not ideal that busybox is configured with
redundant apps, but if the user wants to shrink it, it's possible to
provide a custom config.
This partially reverts commit 33c72344a8.

BR2_PACKAGE_BUSYBOX_SHOW_OTHERS is a bit special. When Busybox is
enabled, it is a Busybox option. When Busybox is not enabled, it is a
stand-alone option, forcibly enabled.
So we can safely 'select' it without ensuring (via a 'depends on' or
another 'select') that Busybox is enabled.
However, the name of this option does not express the fact that it is
safe to select it without checking Busybox, which can lead to a bit of
time-consuming head-scratching.
To avoid future puzzlement from an unsuspecting observer, add a a big
fat comment that this option can be selected without any dependency on
Busybox.
