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containing entries for outdated or non-existing images.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.
