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.

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.

Refer to LINUX_KARCH instead of ARCH when bundling DTS files in the image
builder tarball.
While we're at it, also dereference symbolic links when copying as some
kernel architectures contain symbolic links in their DTS directories.
This fixes aarch64 imagebuilders such as brcm2708/bcm2710 ones in particular
as the kernel refers to "aarch64" as "arm64" internally.

Introduce a new location STAGING_DIR_IMAGE which is intended to be used by
bootloader iamges and similar image-related artifacts.
This directory is guaranteed to be persistent across kernel upgrades which
might involve a removal of KERNEL_BUILD_DIR and is guranteed to be bundled
with the image builder.

Rework the bundle-libraries.sh implementation to use a more robust approach
for executing host binaries through the shipped ELF loader and libraries.
The previous approach relied on symlinks pointing to a wrapper script which
caused various issues, especially with multicall binaries as the original
argv[0] name was not preserved through the ld.so invocation. Another down-
side was the fact that the actual binaries got moved into another directory
which caused executables to fail looking up resources with paths relative
to the executable location.
The new library wrapper implements the following improvements:
- Instead of symlinks pointing to a common wrapper, each ELF executable
is now replaced by a unqiue shell script which retains the original
program name getting called
- Instead of letting ld.so invoke the ELF executable directly, launch
the final ELF binary through a helper program which fixes up the argv[0]
argument for the target program
- Support sharing a common location for the bundled libraries instead of
having one copy in each directory containing wrapped binaries
Finally modify the SDK build to wrap the staging_dir and toolchain binaries
which allows to use the SDK on systems with a different glibc version.

With symlink tree some directories are just symlinked which
means IB and SDK end up with a symlink instead of an actual
directory; this fixes the missing files by dereferencesing
the directories instead of copying the symlinks.

The libc and kernel package files moved since the introduction of shared
packages and the changed output directory layout. This causes the generated
ImageBuilder archive to lack the necessary "libc" and "kernel" meta packages,
leading to opkg install errors later on.
