Fix unused variables, parameters, values

Fixes errors from the following Clang-Tidy categories:

- `clang-analyzer-deadcode.DeadStores`
- `clang-diagnostic-unused-parameter`
- `clang-diagnostic-unused-variable`

Most errors are fixed temporarily by commenting out the unused bits and by adding a `FIXME: unused` comment.

The final fix is to either remove the unused bits or to fix the bugs which has to be done by someone who knows the intended behaviour.
