convert c++ -> c
OsmoPCU is the only Osmocom project in c++ (for historical reasons). There's unfinished efforts converting the codebase to C (jolly/outdated_c branch). Would be nice to follow-up and finish those efforts - it would simplify code transfer and re-use.
Note: it doesn't have to be converted all at once - some files can be converted trivially while others might require heavier rewrite.
