47e8a0730f libkas: Reorder cloning commands and add silent mode consistently
The two code paths are unfortunate. Factor out the difference and use a
single run_cmd invocation. This also adds the forgotten -q when using
a reference directory.

17691d2756 Refactored fetching and checking out of missing repos in kas.config
The current implementation did some more hackish solution to work
around some of kas infrastructure, without changing to much.

This patch cleans this up and therefor remove the more obsure part
of the include mechansim.

013af80599 Add support for Isar build system
Isar allows to build Debian-based images using bitbake and the usual
layer structures. It's very similar to OE, we just need to account for
a different init script name.

abc80a8c59 Implement file version and a check when using it
If the configuration file structure changes over time, it might
introduce incompatibilities.

This patch introduces versioning of configuration file.

Configuration files needs to add a 'version' entry into their 'header'
like this:

header:
  version: '0.9'

After loading this file, the version is checked agains kas version.

Every version 'M.m.p' of kas is allowed to load configuration files with
version 'M.m' and all versions backwards up to and including
the '__compatible_version__' from kas/__version__.py

a65a85b373 Added file header section and put 'includes' under it.
In the current configuration file we mix between entries that are file
specific (like includes and later version) and entries that are used by
the rest of kas, that are not file specific (machine, target, repos,
etc.) It might not be obvious to differenciate between those entries.

This patch introduces a header section into the configuration file, to
contain every setting that is specific to the file and not the complete kas
configuration. The 'includes' statement is moved there, because its file
specific.

34dd07e76e added initial implementation of a include handler
Splitting configuration files into multiple files and implementing an
include mechanism allows to handle configurations more flexible and
allowing following scenarios:

 - including kas configuration file from external meta layer into
   own project
 - splitting many different similar configurations into multiple files
   with only a couple of common files

To include file its necessary to add a 'includes' entry into the kas
configuration. To include files from the same repo, do it like this:

-----
includes:
  - ../base/base_include.yml
-----

The path is relative to the current configuration file. If they start
with a path seperator ("/") they are absolute.

To include files from a different repository, do it like this:

-----
includes:
  - file: bsps/my_machine_include.yml
    repo: collected_machines

repos:
  collected_machines:
    url: https://url.to.git.repo/
    revspec: master
-----

You have to make sure that the repository definition is available
in your current file, or in any include that is available at this
point.

Yaml ("*.yml") and Json ("*.json") files are supported.

Included in this patch are also some changes to the configuration
file structure. Here is an overview:

The value of the 'repos' key is a dictionary that maps a repo identifier
to a dictionary that contains 5 entries:

- url: The url to the repository. If that is missing, no git operations
are used
- refspec: The git refspec of the repository that is used. If that is
missing the latest commit of the default branch is used.
- name: The is defines under which name the repository is stored. If
that is missing the repository identifier is used
- path: The path where the repository is stored. If no url is given and
a path is missing, the repository is referencing the repository under
which the configuration file is stored. If no url is given and a path is
specified, the repository is referencing a directory where layers might
be stored. If an url is specified, path can be used to overwrite the
default (kas_work_dir + repo.name) checkout directory.
- layers: This contains a dictionary of layers, that should be included
into the bblayers.conf. The keys are paths relative to the repository
and the values can be used to exclude layers if they are one of
"excluded", "disabled", "false", "0", "n", or "no". Also boolean values
are accepted. Any other value, including "None" means that this layer is
included into the bblayers.conf. If "layers" is missing or empty, the
repository itself is included into the bblayers. If this is specified, the
repository itself is not included into the bblayers.conf.

c950de46f9 Renamed sublayers back to layers
It was decided that 'sublayers' is to confusing, because this term is
not used in the bitbake/openembedded context.

c65657cac6 Remove state tracking, use KAS_WORK_DIR env variable
Config.has_changed didn't work reliably so far, so the state cache was
only allowing to associate a work directory with configuration file.
However this was rather unintuitive, specifically when moving the work
dir to a different home - nothing told the user about the persistent
association.

We therefore agreed to remove the state cache for now. It can be
reintroduced at any time once a consistent usage model exists.

To establish a relationship to a work directory inside a shell session,
kas now evaluates the KAS_WORK_DIR environment variable.

81a30bc600 Added SHELL and TERM to environment whitelist and start $SHELL if set
Currently the shell provided via the 'shell' command is always '/bin/sh'
and does not have a TERM variable set. This is a rather spartan shell
experience.

With this patch we add the TERM variable to the whitelist, so that
pagers work better and made the shell binary dependent from the SHELL
environment variable. If no such variable is set, we fall back to using
'/bin/sh'.

bb2e98344a Added 'SSH_AGENT_PID' and 'SSH_AUTH_SOCK' to environment whitelist
The ssh-agent environment variables of an ssh-agent that is running
outside the kas build system are not transfered to the bitbake
environment. This causes fetching of private git repositories to
fail.

This patch adds those variables to the environment whitelist.
