This replaces the previous arclint linter for checking the copyright
year in license headers with a gitea workflow job.
As the date of last edit might differ from commit date due to reverts
the copyright linter is run against a base commit.
The python script doing the heavy lifting is written by @Dunedan.

Add a workflow for linting and add a cppcheck job.
The job is using cppcheck provided by package manager. Existing errors
are suppressed to get going with CI linting, ideally tho the suppression
list would be empty. Some of the suppressed errors are only found with
more recent cppcheck than what is available in the runner.
Also remove old arclint cppcheck setup.
