Fix issues found by clazy and clang-tidy

- Call static member functions directly instead of through an instance that
  needs to be fetched
- Avoid C style casts
- Don't use elses after return
- Mark an overridden member function final
- Initialize members
- Use nullptr instead of 0
- Define trivial destructor with "= default"
