This commit follows commit ad501b66. Start up of the busybox logging
daemons were moved to an init script but the shutdown were still
performed in inittab. This commit moves the shutdown policy to an
rcK script that calls the stop function of all the init scripts in
a reversed order.

An initramfs is in fact the same as a cpio archive, but embedded in
the kernel. So instead of duplicating the cpio infrastructure,
we can simply build images/rootfs.cpio and link that into the
kernel.

Devtmpfs doesn't get automounted by the kernel when an initramfs is used.
Since cpio archives are used almost exclusively as an initramfs, the same
fix should be applied to it as for the initramfs.

As the kernel doesn't automatically mount devtmpfs when an initramfs
is used, commit 424888e474 has
introduced a small wrapper script that mounts devtmpfs before starting
the real init.
Unfortunately, the problem is that in this case, the init process runs
without any 0, 1 and 2 file descriptors, so none of the
messages/errors printed by the various initialization scripts can be
seen. This is due to the fact the init process relies on 0, 1 and 2
being opened by the kernel before init is started. However, as
/dev/console isn't present on the filesystem at the time the kernel
tries to open the console to create the 0, 1 and 2 file descriptors,
the kernel fails on this and prints the famous "Warning: unable to
open an initial console".
The proposed workaround is to actually open 0, 1 and 2 to /dev/console
in the wrapper script, right after mounting the devtmpfs filesystem,
and before starting the real init. The "Warning" from the kernel is
still shown, but at least the messages from the init scripts are
visible.

Devtmpfs (which is used by devtmpfs/mdev/udev options) doesn't get

This allows to have a device table for all directories/files and
another device table for the device files themselves. Both are needed
for static /dev, but only the first one is needed when
devtmpfs/mdev/udev are used.

format in a common location, package/makedevs/README.

Four methods for the creation of device files in /dev are now
proposed:
- static method uses device table as before
- devtmpfs method enables this feature in kernel
- mdev method adds mdev starting script to the file system
and selects mdev itself for installation
- udev method selects udev for installation
All dynamic methods are based on devtmpfs, so one doesn't need to care
about /dev folder.
