This exception is always thrown with both a message and a file name.
Combine them to a single string, instead of throwing tuples.

The application should not be stopped from this code, removed `sys.exit`
and added exceptions to improve error handling.
Also added some more checks that were missing.

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

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.

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.
