olddefconfig is a new target available in kconfig that allows to take
an old .config file, and update it to the latest version of the code,
without being asked for questions: it automatically assumes the
default value for options whose value was not defined.
It for example allows to take a minimal defconfig, copy it as .config,
and do 'make olddefconfig' to get the full .config.

We already use the .root stamp file to remember if we have copied the
skeleton, so we can remove the /bin check.
Likewise, we should always have a TARGET_SKELETON (or explicitly error
out otherwise), so remove that check as well.
Finally, now that we're using rsync to do the copy, we might as well
use its exclude support instead of cleaning up unwanted files afterwards.

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.

Store BR2_DEFCONFIG in .config, and use it to update the original input
defconfig file after updating the configuration. When a config is
created by using the BR2_DEFCONFIG=... option, this is saved in the
.config file; later runs of savedefconfig will update that same location.
It is also possible to configure this place in the interactive
configuration.
The BR2_DEFCONFIG value itself is not saved into the generated
defconfig, since Kconfig considers it at its default. This is
intentional, to avoid hard-coding an absolute path in the defconfig.
It will anyway be set again when the defconfig is used with the
'make BR2_DEFCONFIG=... defconfig' command.
As a side-effect of this change, the *config options have been moved out
of the BR2_HAVE_DOT_CONFIG condition. This doesn't make any functional
difference, because the .config is still not read for the *config targets.
However, the defconfig and savedefconfig targets do need to include
.config now, which makes them slightly slower.

users of Eclipse to easily use the toolchain available in
Buildroot. To do so, this plugin reads
~/.buildroot-eclipse.toolchains, which contains the list of Buildroot
toolchains available on the system, and then offer those toolchains to
compile Eclipse projects.
In order to interface with this plugin, this commit adds an option
that allows the user to tell whether (s)he wants the Buildroot project
toolchain to be visible under this Eclipse plugin. It simply adds a

Support scripts (in support/) may need to parse the .config file, so give
them an easy access to it, by exporting BUILDROOT_CONFIG with the fully-
qualified path to .config.
Also, post-build scripts may need to reference a few locations, so export
those, too.
Note: we export both O and BASE_DIR. Although they are the same, BASE_DIR
is used internally, while O is used on the command line, which makes it a
bit ambiguous to know which to use. As users use O= on the command line,
they will probably tend to use that in their post-build scripts.
Update doc accordingly.

A very common mistake done by our users is that they use
output/target/ directory as their root filesystem. Even though this is
loudly documented in our Buildroot manual, people don't read
documentation, so it is not sufficient.
This patch adds a text file named
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why
output/target isn't appropriate to use as the root filesystem. The
process is:
* At the beginning of the build, right after the skeleton has been
copied, support/misc/target-dir-warning.txt is copied to
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM
* In the filesystem images creation code, this file is removed before
launching fakeroot, and restored right after that, so that this
file is not present in the generated root filesystem images.
Note that the file has not been added to the default skeleton for two
reasons:
* It would have annoying to have in our source tree a file named in
capital letters inside system/skeleton/
* The proposed way works even if the user uses a custom skeleton.

This directory groups the following elements:

* 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.

This allows to automatically collect material that may be needed to comply with
the license of packages that Buildroot prepares for the target device.
The core of the implementation is made by the following parts:
- in package/pkg-utils.mk some helper functions are defined for common actions
such as generating a warning, producing info about a package etc;
- in package/pkg-gentargets.mk, within the GENTARGETS framework, a new
<PKG>-legal-info target produces all the info for a given package;
- Makefile implements the top-level targets:
- legal-info-prepare creates the output directory and produces legal info
about Buildroot itself and the toolchain, which mostly means just warning
the user that this is not implemented;
- legal-info, the only target that is supposed to be used directly, depends
on all of the above and finishes things by producing the README files from
the various pieces.

The original 'source-check' target first selects all packages, and then checks
whether the package tarballs can be found. This is useful for Buildroot
maintainers, but less useful for developers working on a specific project. The
latter only care about the packages used in that project.
This patch removes the allyesconfig dependency to source-check so that only
selected packages are checked. The original behavior is moved to a new target
'source-check-all'.
