7f1f9185e7 system: default to devtmpfs for /dev
As discussed on the list, devtmpfs is quite a bit nicer default than
the old static /dev, so change it.

Notice that you NEED to enable CONFIG_DEVTMPFS / CONFIG_DEVTMPFS_MOUNT
in the kernel configuration if you manually build a kernel outside
buildroot, otherwise the rootfs won't work.

ed6912e87d getty: Create specific getty config + cleanups
This commit introduces a specific BR2_TARGET_GENERIC_GETTY configuration flag.
This eliminates the need for checking if BR2_TARGET_GENERIC_GETTY_PORT is an
empty string or not. It also allows hiding various getty options when getty
isn't enabled.

b7c0041c31 kmod: does not support static builds
Since kmod 14, the support for building a static library has been
removed completely from kmod. Therefore, we mark kmod as
!BR2_PREFER_STATIC_LIB, as well as all its reverse dependencies, which
includes the option to use the "udev" /dev management method.

[Peter: show comment for udev when BR2_PREFER_STATIC_LIB is enabled]

59e0692095 host-mkpasswd: new package
Since the addition of root password setting support in buildroot, there have
been a few bug reports in this area ([1], [2]). In these cases, the system
mkpasswd did either not work, or did not provide the options we expect, like
-m <method>.

This patch adds a mkpasswd host package, based on the sources from whois. When
a non-empty root password is set, this package is used as a dependency.

3e56504d9f group file: define groups expected by udev
udev-182 requires several groups to be resolvable at udev startup,
including disk, cdrom, floppy, tape, audio, video, lp, tty, dialout,
and kmem.  Only some of these are in the default skeleton's group
file, So let's add the missing groups, and plugdev too.

This avoids getting these logs in /var/logs/messages:

f1f97b3a05 system: add option to pass extra args to post-build and post-image scripts
It can be useful to have different configuration use the same post-build
and/or post-image scripts as they share a common infrastructure, but yet
have minor differentiation.

This option allows passing zero or more additional arguments to each
post-build or post-image script.

The same set of extra arguments are passed to all scripts, it is not
possible to pass different arguments to each script.

[Peter: fix help text, post-image gets called with the images dir]

2f2bf6a800 system/permissions: make /root group+others non-writable
Upon logging, dropbear whines if /root is group- or others-writable, and
key-based authentication is attempted, reverting to password-based
authentication:
    dropbear[149]: /root must be owned by user or root, and not writable by others
    dropbear[149]: Password auth succeeded for 'root' from 192.168.127.35:41566

On my system, /root was 770. Changing to 700 fixed the issue.

Having /root 700 is a good idea, anyway.

9dab397a4f system/skeleton: remove /etc/hostname
We already provide BR2_TARGET_GENERIC_HOSTNAME to set /etc/hostname,
so a default /etc/hostname file isn't needed.

More importantly, if the user has explictly set BR2_TARGET_GENERIC_HOSTNAME
to the empty string, we would still end up with a /etc/hostname containing
'buildroot' which is unlikely to be what the user wanted.

d67b3a54af skeleton: add default login port to /etc/securetty
We ran into a "Login incorrect" problem when running the same rootfs
image across platforms with different loging ports ttyS0/1/2/3.

Simply assignning "console" to BR2_TARGET_GENERIC_GETTY_PORT, which in
turn modifies the /etc/inittab, is not enough because the "console" device
was missing in the /etc/securetty.

While current securetty has enumerated a lot of ttys, this patch should save
some efforts to enumerate more.

9fa32ba0b7 Add a post-image script mechanism
Just like we have a post-build script mechanism that gets executed
after the build of all packages but before the creation of the
filesystem images, let's introduce a post-image script mechanism, that
gets executed once all filesystem images have been generated.

This can for example be used to call a tool building a firmware image
from different images generated by Buildroot, or automatically extract
the tarball root filesystem image into some location exported by NFS,
or any other custom action.

select the D-Bus package 'depends on BR2_USE_MMU'.

In addition, for the specific case of gvfs, the missing
BR2_TOOLCHAIN_HAS_THREADS dependency is added (threads are required by
D-Bus, so they are also required by gvfs which selects D-Bus).

6c3e3ad419 New top-level directory: system
This directory groups the following elements:
 * the default root filesystem skeleton
 * the default device tables
 * the Config.in options for system configuration (UART port for
   getty, system hostname, etc.)
 * the make rules to apply the system configuration options

Even though the skeleton and device tables could have lived in fs/, it
would have been strange to have the UART, system hostname and other
related options into fs/. A new system/ directory makes more sense.

As a consequence, this patch also removes target/Makefile.in, which
has become useless in the process.
