Closes#2737
Use PATH_MAX rather that 128 for path buffers. Patch from kernel 1408b15b98
(kconfig: Use PATH_MAX instead of 128 for path buffer sizes) by Will Newton.

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).

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.

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

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.

This also provides a nice up-to-date filestamp if something got reconfigured (e.g. c++ support got toggled) that can be used in the future to depend accordingly.
The configuration utility in package/config/ can look for a default
configuration file called 'defconfig' but it's hard coded to look for
sysdeps/linux/defconfig.
This patch causes the config utility to look in the current working directory
for the 'defconfig' file. I use this to provide a default configuration to a
new buildroot environment. This way, I can 'svn co' buildroot, copy my
defconfig, then make defconfig to use my own default configuration.
This fix only changes one line in the confdata.c file to remove the legacy path
that was used in Linux, and not needed in buildroot.
