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:

("merge_config.sh: Allow to define config prefix")

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
...
$ cd output
$ echo 'BR2_TARGET_GENERIC_HOSTNAME="test"' > test.frag
$ ../buildroot/support/kconfig/merge_config.sh .config test.frag

Pass BR2_EXTERNAL value via -e option.
This will prevent merge_config.sh from silently eating any symbols defined in
external trees on a clean buildroot tree invocation.

Creating temporary files in /tmp (or the path pointed by $TMPDIR) allows the
buildroot top directory to be read-only and shareable between multible builds.
This follows what other scripts do, e.g. check-kernel-headers.sh.

With this, we can trash our probability patch, it's now upstream.
Refresh a few other patches.

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.
