Lock files are now using the commit key, rather than legacy refspec, and
the plugin writes out flattened configs that are in line with the input
configs (only write refspec if input repo was using refspec).
This also requires slight adjustments of the related test case. Enhance
the dump test at this chance to actually validate the written commit ID
against the expected one.

This allows to clearly express if a refspec is a commit ID or a
branch/symbolic reference. Mixing repos with old refspec with repos that
uses new commit/branch is supported, but not mixing the keys in the same
repo.
This commit lays the ground by extending the schema and ensuring that
the code which at minimum needs to know about these new keys does so.
Existing tests still pass, new ones will follow.

If a refspec addresses an upstream branch which commit happens to be
local already, checkout will not properly replicate that into a local
branch. Extend contains_refspec_cmd so that it does not falsely report
the remotes/origin/ ref as locally available and rather triggers its
fetching.

If a remote branch is referenced as refs/heads/<branch>, also drop the
heads/ from the local branch name to have a consistent naming.
This wasn't noticed so far because the primary use case of refs/ is

When using the kas menu command, we need to track the repository
location outside of the kas container as well. This is required to
prepare the environment for a later kas-container build, as the repo
path inside the container is different from the outside one. For that,
the location of KAS_REPO_DIR is passed via an env-var into the container.
There, this value is picked up by the menu plugin and written to the
.config.yaml file as `_source_host_dir`. When running kas-container build,
we check if the .config.yaml file contains this node and set the
KAS_REPO_DIR accordingly. The schema is extended accordingly.

This patch adds a new top-level schema node `_source_dir` which is used
to track the top repo dir on auto-generated kas files. This node is
generated by the kas menu plugin and provides the absolute path to the
top repo dir at time of invoking the plugin. When later calling any other
kas operation that performs a checkout, this node is evaluated and the
top repo dir is set accordingly. This tracking is required when the
build command is executed from another dir than the top repo dir, as the
repo-dir cannot be computed by kas in this case (the .config.yaml file
is in the KAS_WORK_DIR, not in the repo dir).

When async tasks fail, all exceptions need to be collected to not get
subsequent exceptions about invalid future states. This is achieved by
gathering the task results, instead of just waiting for them. By
gathering the results, also user-requested cancellation (e.g. via
ctrl-c) works without throwing tons of additional exceptions.
Since ac437308 we more likely run into that case, which unvealed the bug.
By properly handling the exception, a TaskResultError is returned
instead of the underlying CommandExecError. This change is reflected in

This patch adds the --lock option to the dump plugin. When enabled, the
output only contains the resolved refspecs of each repo (as valid kas

and these can be pinned to fixed revisions, when required.
When using --lock in combination with --inplace, a lockfile named

multiple files are added to the kas CLI, the lockfile is only created
for the first file (by considering the merged information from all files).

This patch adds the top-level `overrides` entry, which is used to
override (or pin) the refspec of repositories. The main difference to a
direct override is that this logic only applies to repos that are
already defined. By that, a superset of all repos can be added to this
entry (similar to a global lockfile), but only the currently active ones
are affected. A new top-level keyword is required because everything
below the "repos" keyword is potentially defined by "default" values.
For the locking mechanism, a clear separation between overrides (only
override if existing) and definitions is required to be able to define a
global lockfile with all possible repos, while just defining some repos.

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 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.
