savedefconfig will save a minimal config to a file
named "defconfig".

The config symbols are saved in the same order as
they appear in the menu structure so it should
be possible to map them to the relevant menus
if desired.

The implementation was tested against several minimal
configs for arm which was created using brute-force.

There was one regression related to default numbers
which had their valid range further limited by another symbol.

Sample:

config FOO
	int "foo"
	default 4

config BAR
	int "bar"
	range 0 FOO

If FOO is set to 3 then BAR cannot take a value higher than 3.
But the current implementation will set BAR equal to 4.

This is seldomly used and the final configuration is OK,
and the fix was non-trivial.
So it was documented in the code and left as is.

This patch was inspired by the kernel projects page, where an ncurses
replacement for menuconfig was mentioned (by Sam Ravnborg).

Building on menuconfig, this patch implements a more modern look
interface using ncurses and ncurses' satellite libraries (menu, panel,
form). The implementation does not depend on lxdialog, which is
currently distributed with the kernel.

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.

Those two functions are
	void sym_set_change_count(int count)
and
	void sym_add_change_count(int count)

All write accesses to sym_change_count are replaced by calls to above
functions.

Variable and changer-functions are moved to confdata.c.  IMO thats ok, as
sym_change_count is an attribute of the .config's change state.

I made a patch that detects if libintl.h (needed for nls) is present on the
host system and if it's not, it nls support is disabled by providing
dummies for the used nls functions.

This way if there is nls support on the host system the *config targets
will build according to Arnaldo Carvalho de Melo's i18n modifications, else
it just uses the original English messages.

I have also made a bug report at kernel's bugzilla:
http://bugzilla.kernel.org/show_bug.cgi?id=5501

Replace all menu_add_prop mimicking menu_add_prompt with the latter func. I've
had to add a return value to menu_add_prompt for one usage.

I've rebuilt scripts/kconfig/zconf.tab.c_shipped by hand to reflect changes
in the source (I've not the same Bison version so regenerating it wouldn't
have been not a good idea), and compared it with what Roman itself did some
time ago, and it's the same.

So I guess this can be finally merged.

This patch adds i18n support for make *config, allowing users to have the
config process in their own language.

No printk was harmed in the process, don't worry, so all the bug reports,
kernel messages, etc, remain in english, just the user tools to configure
the kernel are internationalized.

Users not interested in translations can just unset the related LANG,
LC_ALL, etc env variables and have the config process in plain english,
something like:

LANG= make menuconfig

is enough for having the whole config process in english. Or just don't
install any translation file.

Translations for brazilian portuguese are being done by a team of
volunteers at:

http://www.visionflex.inf.br/kernel_ptbr/pmwiki.php/Principal/Traducoes

To start the translation process:

  make update-po-config

  This will generate the pot template named scripts/kconfig/linux.pot,
  copy it to, say, ~/es.po, to start the translation for spanish.

To test your translation, as root issue this command:

  msgfmt -o /usr/share/locale/es/LC_MESSAGES/linux.mo ~/es.po

  Replace "es" with your language code.

  Then execute, for instance:

  make menuconfig

The current patch doesn't use any optimization to reduce the size of the
generated .mo file, it is possible to use the config option as a key, but
this doesn't prevent the current patch from being used or the translations
done under the current scheme to be in any way lost if we chose to do any
kind of keying.

Thanks to Fabricio Vaccari for starting the pt_BR (brazilian portuguese)
translation effort, Thiago Maciera for helping me with the gconf.cc (QT
frontent) i18n coding and to all the volunteers that are already working on
the first translation, to pt_BR.

I left the question on whether to ship the translations with the stock kernel
sources to be discussed here, please share your suggestions.

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!
