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.
