Fix memory leaks by making `AddOption` unconditionally duplicate passed in strings, taking ownership. Callers using dynamic memory free their storage after calling `AddOption`. This ensures no memory is dropped on the floor. This also removes the second argument to `AddOption` as it is unused and shifts it into the source file.
