Use PATH_MAX rather that 128 for path buffers. Patch from kernel 1408b15b98

This re-instates writing the version string in .config headers, and no
longer provides it as a kconfig symbol in .config (it is now a variable
in the Makefile, and in the environment).

We use BR2_*, not CONFIG_* - So remove references to CONFIG_ in search/help
windows.
Long term we should probably consider doing s/^BR2_/CONFIG_/ to get rid
of all this though.

Those hacks should not be needed and they even make "mconf" fail to
save the configuration file in $(CONFIG_DIR).

The goal is to be able to use savedefconfig to generate minimal
defconfig files.
Four of our patches are removed since the modifications have been
merged upstream. The new nconf configuration utility has appeared.

Our kconfig-to-buildroot2.patch hasn't been kept up to date with all
the changes made into package/config, and a single patch wasn't very
practical to maintain all our changes. Therefore, this commit adds a
package/config/patches directory, which contains a Quilt series of
patches that correspond to our modifications to the kconfig mechanism.
The huge kconfig-to-buildroot2.patch has been split into 16 smaller
patches. The purpose of some of the modifications has been clearly
identified, while some others were not identified.
The 16 patches together do match exactly the old
kconfig-to-buildroot2.patch. We have been very careful in making sure
that we wouldn't loose any of our modifications.
The only modifications made are :
* Instead of renaming the kernel Makefile to Makefile.kconfig and
naming the Buildroot Makefile just 'Makefile', we instead keep the
original package/config/Makefile from the kernel
scripts/kconfig/Makefile and name the Buildroot Makefile
package/config/Makefile.br. The main Buildroot Makefile is modified
accordingly.
* The documentation README.buildroot2 is updated to explain how to
upgrade to a newer version of scripts/kconfig.
* The kconfig-language.txt documentation is removed, as anybody can
easily find it in the kernel sources so there's no need to
duplicate it here.

rand{,package}config enables configuration options with 50% probability,
which isn't always what we want in BR (because the "big" configs take a
long time to build and limits the chance of a randconfig detecting a
missing dependency), so introduce a KCONFIG_PROBABILITY environment
variable to tweak the probability between 0 (all options off) and 100
(all options on).
To use, simply set the environment variable before running make or pass
it on the make command line - E.G.
make randpackageconfig KCONFIG_PROBABILITY=10

We don't actually need to explicitly clean the kconfig stuff, as distclean
already removes the entire BUILD_DIR, but fix up the packag/config makefile
to do the right thing if make clean/distclean is called manually for
completeness.

Support the GTK variant of the graphical kconfig configurator as an
alternative to the Qt3-based one.
Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
Since the recent update of Kconfig to the Kconfig infrastructure found
in 2.6.30 kernels, make oldconfig was broken because it didn't
generate the .config.cmd file. This is done by a call to the
conf_write_autoconf() function.
Moreover, this process was also broken because the
conf_get_autoconfig_name() function was reading the environment
variable BUILDROOT_AUTOCONF while the main Makefile is passing it as
KCONFIG_AUTOCONFIG. We also remove the fallback on
"$(BR2_DEPENDS_DIR)/config/auto.conf" since we are not able to expand
BR2_DEPENDS_DIR at this point. Therefore, the KCONFIG_AUTOCONFIG
envionment variable *must* be set.

The update of kconfig and the addition of xconfig support generates
more files in package/config/. Tell git to ignore them.
Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
It involved:
* Modifying the top-level Makefile to create the xconfig target, and
the $(CONFIG)/qconf target to compile the qconf utility
* Modifying the package/config/Makefile magic so that C++ files and
binaries gets linked properly, re-using the
package/config/Makefile.kconfig logic inherited from the kernel
* Hacking a little bit package/config/Makefile.kconfig in a way
similar to the modifications done for the mconf (menuconfig
interface)

Don't use this, it doesn't work yet. Thoughs welcome.
Like: We should probably use the sym->text and not fiddle with the name since
the name looses information ('_' != '-' in host-fakeroot). This would not
be too robust, i fear, since the name can contain additional, arbitrary info.
Also, the real 'depends' are a little bit ugly in kconfig. There doesn't seem
to be a nice property that holds reverse deps that are only contain selected
symbols.
Thoughts?
