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.

The default sysvinit inittab does two separate mkdir calls to create
/dev/pts and /dev/shm. Reduce this to call mkdir only once for both
directories.
This removes id "si3" but keeps ids "si4".."si9" intact rather than
renumbering them. This would just increase the turmoil without any
practical effect.
Based on commit e9db8122fb, by Florian La Roche <F.LaRoche@pilz.de>.

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].

Closes #8911
When the kernel passes single in the command line, this translates
into an init -s option that is suppose to drop into a shell after
the sysinit and before the runlevel.
So, in busybox this is hardcoded - but, in sysvinit using the
sysinit action for the rcS means that it will always be executed
even when trying to get into single user mode for repair.
This change should run rcS in all of the expected runlevels
1-5 and should achieve the desired result compared to the busybox
and still allow a single user shell to get started as expected
before running rcS.

Most embedded systems do not have a keyboard.
If a keyboard is attached afterwards (e.g. to an accessible USB host port)
this allows the user to reboot the system by pressing Ctrl-Alt-Del, which
might not be desired.

The previous shutdown sequence was basically a no-op, it did't call rcK
to stop anything and dumped users back into shell.
So do the proper thing by calling rcK for levels 0 (halt) and 6
(reboot), then swapoff, then remount ro.
After that call halt for 0 and reboot for 6.
Also make 3 the default runlevel as in normal distributions, for all
intents and purposes it changes nothing except aesthetics/convention.
And make the labels a context sequence rather than just a short form
of the actions which IMHO looks horrible.

Update inittabs (skeleton/busybox & sysvinit) to remove the trailing
REMOUNT_ROOTFS_RW comment used as magic string in system/system.mk to
enable/disable remounting the root filesystem rw or not since it affects
sysvinit in doing so properly as reported in bug #7442.
Instead update the sed expressions to match clean non-commented strings
by searching for "-o remount,rw /" and checking that's the end of the
line as well to avoid affecting possibly other remounts that a user can
have in a custom inittab.
Long-term the startup block of inittab should just move to a S00sysinit
script or similar so that rcS can pick it up directly.

Don't try to start logging from /etc/inittab because busybox installs a
S01logging script that handles that and can lead to duplicate logging
processes.
Let's handle the logging in each package that provides it since we can
get multiple variants in the future like syslog-ng that have different
initialization routines.

The correct capitalised form appears to be "BusyBox" rather than "Busybox";
fix all references to the latter form. (Most such references occur in the
manual and in commentary in package makefiles.)

Adding support for sysvinit to install reboot, poweroff, and pidof
commands available in /sbin.
Fixes bug #6620
Removed uninstall commands since they aren't used.
There is an error with sysvinit that will prevent the system from booting
if "dshm::sysinit:/bin/mkdir -p /dev/shm" is not present in the inittab.
