config FOO
string
default "foo"

Help text for certain config options is very extensive (the text
includes the names of all other options the option in question depends
on). Long lines are not wrapped, making it impossible to see the list
without scrolling horizontally.
This patch adds some logic which wraps help screen lines at word
boundaries to prevent truncating.
Tested by running
ARCH=powerpc make menuconfig O=/tmp/build
which shows that the long lines are now wrapped, and
ARCH=powerpc make xconfig O=/tmp/build
to demonstrate that it still compiles and operates as expected.

Regardless of KCONFIG_AUTOCONFIG, the filename written as a Make target
into "include/config/auto.conf.cmd" was always the default one.
Of course this doesn't make it work for the Kernel kbuild system, since
there the filename is hardcoded at several places in the Makefiles.

1) The field 'len' of the 'gstr' structure seems to track the size of the memory
already allocated for the "growable string". So the value of this field should be
the same as the 'malloc()' just above, shouldn't it ?

Add the possibility to import a value from the environment into kconfig
via the option syntax. Beside flexibility this has the advantage
providing proper dependencies.
Documented the options syntax.

With specific configurations requesting help for certain
menu lines caused menuconfig to crash.
This was tracked down to a null pointer bug.
Thanks to "Miles Lane" <miles.lane@gmail.com> for inital reporting
and to Gabriel C <nix.or.die@googlemail.com> for the backtrace
that helped me locating the bug.

This fixes one of the worst kbuild warts left - the broken dependencies used
to check and regenerate the .config file. This was done via an indirect
dependency and the .config itself had an empty command, which can cause make
not to reread the changed .config file.
Instead of this we generate now a new file include/config/auto.conf from
.config, which is used for kbuild and has the proper dependencies. It's also
the main make target now for all files generated during this step (and thus
replaces include/linux/autoconf.h).
This also means we can now relax the syntax requirements for the .config file
and we don't have to rewrite it all the time, i.e. silentoldconfig only
writes .config now when it's necessary to keep it in sync with the Kconfig
files and even this can be suppressed by setting the environment variable
KCONFIG_NOSILENTUPDATE, so the update can (and must) be done manually.

If the file .kconfig.d is missing then make sure to run
'make silentoldconfig', since we have no way to detect if
a Kconfig file has been updated.
-kconfig.d is created by kconfig and is removed as part
of 'make clean' so the situation is likely to occur in reality.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
