Initializes the global config.
There are multiple sources which are used to init the config:
* ``configFilename``, and maybe first item of ``commandLineOptions`` interpret as config filename
* other options via ``commandLineOptions``
* ``extra_updates``
Note about the order/priority of these:
* ``extra_updates``
* options from ``commandLineOptions``
* ``configFilename``
* config filename from ``commandLineOptions[0]``
* ``extra_updates``
* options from ``commandLineOptions``
``extra_updates`` and ``commandLineOptions`` are used twice so that they are available
when the config is loaded, which thus has access to them, and can e.g. use them via Python code.
However, the purpose is that they overwrite any option from the config;
that is why we apply them again in the end.
``commandLineOptions`` is applied after ``extra_updates`` so that the user has still the possibility
to overwrite anything set by ``extra_updates``.
