We are using empty CONFIG_PREFIX_. This results in false positive match
for comment lines when merging config fragments.
To avoid false positive reports, we use separate sed expressions and
address comment lines explicitly.
This is actually is in the Linux kernel mainline (v4.20-rc2):

This patch allows us to define config prefix with CONFIG_ environment
variable.
By setting the proper config prefix, we will have proper 'redundant
configuration warnings' when we use '-r -m' options.
This is actually already in mainline for v4.20-rc1:

Commit 6eacea5ae0 accidentally removed these changes in merge_config.sh:
0f56304521 ("merge_config.sh: create temporary files in /tmp")
28fac3973b ("merge_config.sh: add br2-external support")
Changes were lost because commits just changed files, but didn't add patches.
Therefore not only restore our changes, but also add (updated) patches.
Missing 0f56304521 caused breaking merge_config.sh when used in out of
tree build:
$ make -C buildroot O=$PWD/output defconfig

Buildroot's "make nconfig" command stopped working a while ago on
Gentoo systems. Running the command would result in a crash.
The issue is caused by lxdialog's cflags which are also used to build
nconfig; It would detect *ncursesw* and turn on WIDECHAR support --
but the Makefile would still link to plain *ncurses* while building
nconfig (which was built without WIDECHAR support).
This would cause a crash after using *wattrset* on a WINDOW instance.
WIDECHAR *wattrset* would try to set the _color member in the WINDOW
struct which does not exist in the NON-WIDECHAR ncurses instance. It
would end up clobbering data outside the struct (usually _line entries).
An upstream patch fixes the issue, so we're applying it to Buildroot's
kconfig.

This makes "make menuconfig" also work on systems where ncurses is not
installed in a standard location (such as on NixOS).
This patch changes ccflags() so that it tries pkg-config first, and only
if pkg-config fails does it go back to the fallback/manual checks. This
is the same algorithm that ldflags() already uses.
[This patch is already applied upstream (is part of linux v3.18):
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=be8af2d54a66911693eddc556e4f7a866670082b
I'm adding this instead of doing a full upstream kconfig sync because
there was a conflict in one of the Buildroot kconfig patches (against
linux 3.18-rc1), which I was unable to resolve. Just drop this patch next time
Buildroot kconfig is synced against upstream.

Patches 02-cpp-comments-to-c-comments.patch changes C++-style comments
into C-style comments.
This is unneeded, since gcc accepts C++-style comments in C code anyway.
Ditch that patch, that's one less we have to handle when updating from
upstream.

In case a menu has comment without letters/numbers (eg. characters
matching the regexp '^[^[:alpha:][:digit:]]+$', for example - or *),
hitting space will cycle through those comments, rather than
selecting/deselecting the currently-highlighted option.
This is the behaviour of hitting any letter/digit: jump to the next
option which prompt starts with that letter. The only letters that
do not behave as such are 'y' 'm' and 'n'. Prompts that start with
one of those three letters are instead matched on the first letter
that is not 'y', 'm' or 'n'.
Fix that by treating 'space' as we treat y/m/n, ie. as an action key,
not as shortcut to jump to prompt.

It's now been a while since it has been possible to build the kconfig
parser to understand a prefix other than CONFIG_, and even no prefix
at all, by setting the CONFIG_ macro (#define) at biuld time.
Just use that, insted of patching, it will make it easier for us in the
future.
Our patches have been refreshed at the same time.

Our kconfig code is updated to the version of kernel 3.9-rc2. No major
issues during the migration, except:
* Some conflicts when applying 03-change-config-option-prefix.patch
due to upstream kernel changes.
* The need of adding a new patch, 15-fix-qconf-moc-rule.patch, to fix
the make rule that generates the moc file for the Qt-based
interface.
