Summary: `addObserver` and `removeObserver` now accepts const references instead of pointers which indicates the intent (non-nullability and non-owning) clearly. The delegate methods are also marked as `const` to designate the possible concurrent execution (`const` means "thread-safe" here). All changes are pure syntactical, nothing really changes (besides the fact overall code quality and redability).
