This is for the sake of the gitlab-ci runner which does not properly
aligns the ownership of the repo it checks out with the UID:GID of
our builder user. Reason not yet understood and hard to debug (logging
of the runner is incomplete).
Work around this issue by disabling safe.directory checks in case the
container is called without kas-container as wrapper (means, when it is
called without setting "--user=root"). This preserves git's checks for
the common interactive case, the more critical one.

Already create the builder user/group during container image build and
only align the IDs in the entrypoint if started with a non-zero USER_ID.
The primary gain is code simplification because this removes some
dynamics from the entrypoint.
As this refactoring avoids that gitlab-ci runners start the container as
root, it was also supposed to resolve the mismatch between the owner of
the checked-out repo and builder user. Unfortunately, this does not work
yet, and the reason is still unclear.

Leave the isar-only commands commented-out in the container-entrypoint
and simply remove the comment when building kas-isar. This is simpler,
more readable and also more robust against changes of the entrypoint
file.
While at it, avoid a separate layer for modifying container-entrypoint.

The current detection mechanism assumes that if the docker command
is available the engine behind is also docker. In fact nowadays a
lot of people use /usr/bin/docker as an alias for podman. In that
case the script expects a docker engine and misses to use
podman-specific settings.
To fix this, run "docker -v" and check if the output indicates a
podman engine or a real docker engine. Otherwise error out as the
enginge is not supported.

This patch reworks the logic when setting KAS_REPO_REF_DIR.
When this variable is set, a two-staged clone is used:
First, a bare-clone (or similar) is created in the ref-dir, according to
the naming scheme. This clone is executed in a way that is both
reentrant as well as race-free across multiple instances of KAS working
on the same dir. Internally we clone into a tmpdir below the refdir and
rename on success to guarantee the atomicity of the operation on POSIX
compliant filesystems.
Second, the clone in the KAS_WORK_DIR is executed against the local
copy. After that, the origin url is redirected to the upstream url.
By that, the KAS_REPO_REF_DIR directory can be cached across builds
which significantly speedsup clone times against large repos.
In case the requested refspec is already in the cache (very likely in CI
builds), no direct access to the upstream repo is required. This logic
is crucial for CI systems in China, where e.g. access to github is
blocked from time to time.
The clone-from-local logic is currently only implemented for the git plugin
as HG misses the caching logic. Repo implementations that do not support this
logic can simply opt-out for the first stage by returning 'true'.
The existing user-facing logic of KAS_REPO_REF_DIR is not affected.
However, internally we no longer clone via --reference as this still
requires access to the remote repo, even if the requested commit is
already in the local copy.

This patch adds a flag --resolve-refs to the dump plugin.
Once enabled, all relative refspecs (e.g. branch or tag names) are
resolved and replaced by their exact revision (before patches are
applied).
When re-running kas on the flattened and expanded config file, the build
is executed against exactly the versions of the dependencies that where
used when dumping the configuration. This helps to keep track of build
versions for future use (e.g. reproducible builds) or for
version-tracking tools like renovate.

This patch adds a programmatic attribute 'revision' to the repo class.
This attribute contains the exact revision at the time of the checkout
of a repository. By that, we can avoid the ambiguity of refspecs
containing tags or branch names. Internally, the revision is not yet
used but just made available for future downstream users (e.g. plugins).
Note, that the revision has to be re-queried on each access, as the
Config class re-instantiates the repos for each consumer.

This patch adds a new plugin 'dump' which resolves all kas config
includes and combines them in a single file. The format of the output
file can either be JSON or YAML. In case of YAML, the generated config
fulfills the kas-config schema and can be used as input to kas again.
In addition, the generated files can be used by external tools to
analyse the dependencies and versions of the project.
While the generated configuration is semantically identical to the
input config, we do not guarantee binary compatibility as especially
YAML provides multiple ways to serialize strings and null values.
Not giving this guarantee makes it easier to evolve and maintain the plugin.
The plugin itself extends the checkout plugin, as referenced repos have
to be checked-out first to resolve cross-repo references. This also
requires, that the declared refspec of all referenced repos can actually
be found and checked out.

Container engines per default log all container output into journald
(Podman) or a json file (Docker).
A build with kas-container/bitbake containes lots of useless build
output like progress lines, etc.
In case of Podman, where journald is used, this means that all this is
spammed into the journald buffer and possible also send to ttys or even
serial ttys. This might make sense for containers that output only
status information about running services, but for a build process, this
is mostly just spamming and causes important information to be lost.
Since the stdout/stderr output of the container is used for
kas-container ordinarily, the background logging from the container
image can be deactivated.
Therefor add the `--log-driver=none` parameter to all container
runtimes command lines.
