GitLab

The legacy API is has been (internally) ported to use the new interface.
The intent is that users of the legacy API do not have to change their
codes.

Next step is to completely adapt the .gitlab-ci.yml file

Two issues: executable was named differently and the CI test names were
colliding

added several larger tests in CI. Still missing for gfortran (no
gfortran+cuda tests at the moment, will be added)

some intent (in) or (out) added
some comments added
