When using external targets there is a symlink being created for the
target under target/linux which then becomes dangling under Image
Builder. Fix it by dereferencing the possible symlink.
Tested on IB with external target, ipq40xx and mvebu.

This commit fixes commit "2999f810ff: build,IB: include kmods only in
local builds" which cause the local packages/ folder only to be added
for local builds but no longer for ImageBuilder created by the Buildbot.
The commits intention was to use remote kmods repositories rather than
storing them locally. Accidentally the entire handling of the local
`packages/` was removed.
Re-add the folder and include a README describing what it can be used
for.

Using these config-options to customize the folders used at build-time
makes these folder settings appear in generated archive. This causes the
imagebuilder to be not portable, as it's going to use the build-time folders
on the new systems. Errors look like:
mkdir: cannot create directory '/mnt/build': Permission denied
Makefile:116: recipe for target '_call_image' failed
make[2]: *** [_call_image] Error 1
Makefile:241: recipe for target 'image' failed
make[1]: *** [image] Error 2
The build-time settings of these folders are passed into the archives via
.config file.
The expected behavior is that after unpacking the imagebuilder acts like
these settings have their defaults, using intree folders. So unset the
build-time settings.

The ImageBuilder `make manifest` prints all installed packages. This
function can be used to create a list of package and corresponding
package versions before attempting image creation.
When called with `--strip-abi` OPKG can automatically strip attached
ABIVersions from package names. Make this function accessible for the
ImageBuilder by adding a `STRIP_ABI` variable.

Invoke bundle-libraries.sh with any buildroot related directory entries
removed from $PATH to avoid picking up cross versions of utilities like
ldd which will not properly work when used against host executables.
This should fix executable bundling for glibc-target imagebuilders.

When building images with the imagebuilder, the partition signature
never changes. The signature is generated by hashing SOURCE_DATE_EPOCH
and LINUX_VERMAGIC which are undefined. Prepopulate these variables, as
done by the SDK.

The ImageBuilder downloads pre-built packages and adds them to images.
This process uses `opkg` which has the capability to verify package list
signatures via `usign`, as enabled per default on running OpenWrt
devices.
Until now this was disabled for ImageBuilders because neither the `opkg`
keys nor the `opkg-add` script was present during first packagelist
update.
To harden the ImageBuilder against *drive-by-download-attacks* both keys
and verification script are added to the ImageBuilder allowing `opkg` to
verify downloaded package indices.
This commit adds `opkg-add` to the ImageBuilder scripts folder. The keys
folder is added to ImageBuilder $TOPDIR to have an obvious place for users to
store their own keys. The `option check_signature` is appended to the
repositories.conf file. All of the above only happens if the Buildbot
runs with the SIGNATURE_CHECK option.
The keys stored in the ImageBuilder keys/ are the same as included in
the openwrt-keyring package. To avoid the chicken-egg problem of
downloading and verifying a package, containing signing keys, the keys
are added during the ImageBuilder generation. They are same as in
shipped images (stored at `/etc/opkg/keys/`).
To allow a local package feed in which the user can add additional
packages, a local set of `usign` and `ucert` keys is generated, same as
building OpenWrt from source. The private key signs the local repository
inside the packages/ folder. The local public key is added to the keys/
folder to be considered by `opkg` when updating repositories. This way a
local package feed can be modified while requiring `opkg` to check
signatures for remote feed, making HTTPS optional.
The new option `ADD_LOCAL_KEY` allows to add the local key inside the
created images, adding the advantage that sysupgrades can validate the
ImageBuilders local key.

JSON info files contain machine readable information of built profiles
and resulting images. These files were added in commit 881ed09ee6
("build: create JSON files containing image info").
They are useful for firmware wizards and script checking for
reproducibility.
Currently all JSON files are stored next to the built images, resulting
in up to 168 individual files for the ath79/generic target.
This patch refactors the JSON creation to store individual per image
(not per profile) files in $(BUILD_DIR)/json_info_files and create an
single overview file called `profiles.json` in the target directory.
Storing per image files and not per profile solves the problem of
parallel file writes. If a profiles sysupgrade and factory image are
finished at the same time both processes would write to the same JSON
file, resulting in randomly broken outputs.
Some target like x86/64 do not use the image code yet, resulting in
missing JSON files. If no JSON info files were created, no
`profiles.json` files is created as it would be empty anyway.
As before, this creation is enabled by default only if `BUILDBOT` is set.
Tested via buildroot & ImageBuilder on ath79/generic, imx6 and x86/64.

With the fix of external kmod feeds it is possible to ship the
ImageBuilder without any packages except the pseudo packages kernel and
libc. Therefore the local package feeds becomes optional.
This commit adds a check to the package_reload function to only run if
the local feed is existing.

The buildbots generate a kmod archive which should be used instead of a
local copy. This is possible due to the introduction of a kernelversion
specific feed.
This commit adds the ability of using only signed package feeds.

The package manager `opkg` offers the function `whatdepends` to print
packages that depend on a specific package.
This feature is useful when used in a CI to not only build an upgraded
package but all packages with a dependency.
Usage:
make whatdepends PACKAGE=libipset
The resulting list can be fed into a SDK building all packages and warn
if anything fails.

The folder `json_info_files` contains multiple JSON files which describe
created firmware images. The folder is not removed between builds as the
ImageBuilder does not use `image.mk`.
Not removing the JSON files result in a merged `profiles.json` file
containing entries for outdated or non-existing images.
This commit adds the `json_info_files/` cleanup step to the ImageBuilder
Makefile.

The patch 4a1a58a3 build, imagebuilder: Do not require libncurses-dev
was supposed to remove libncurses as a requirement for the ImageBuilder.
However as the IB=1 is only exported during building, not for checking
requirements, it did never actually work.
This commit export IB=1 to the requirement check.
