This patch removes the special handling of the -h / --help flag for kas
subcommands. By that, the build system detection logic properly works
and runs the help command in the kas-isar container for ISAR kas files.
While this logically does not make any difference, it avoids to pull the
kas OE container for ISAR builds, just to show the help message.

In ac4373088 the error handling was made more strict. By that, failures
during patch apply instantly bailed out instead of returning and

into a more specific exception with a useful error message.

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
the corresponding unit test.

This patch adds the KasUserError exception class to distinguish between
internal kas exceptions and user or configuration errors. Exceptions
previously raised on user errors are ported over by deriving
KasUserError. In case of user errors, only the exception message is
shown, but no stacktrace. This makes it easier for users to locate the
issue as the reason is now stated in the last line of the output.
Kas internal exceptions are not subject to this change to help the
developers to find the root cause more easily.

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
format). By that, floating branches can be used in the projects kas files
and these can be pinned to fixed revisions, when required.
When using --lock in combination with --inplace, a lockfile named
<filename>.lock.<ext> is created next to the <filename>.<ext>. In case
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.

Neither git nor hg currently provide a production-ready replacement for
weak SHA-1 commit IDs. Furthermore, kas mixes commit IDs and symbolic
commit names in refspec. This permits attackers who gained control over
a repository that kas fetches from to present manipulated content
without kas noticing this.
Aditya Sirish A Yelgundhalli recently reported one potential attack
scenario, using branches that shadow commit IDs. While trying to
mitigate this particular case, it became clear that there is no simple
solutions with the given tools and interfaces.
For now, warn prominently that only trusted sources should be used.

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

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.
