Cleanup: Move outliner types to namespace, avoid C-style type definition

With C++ we should transition towards namespaces to avoid naming
collisions. Having the namespace in place is the first step for that
transition.

Plus, the `typedef` isn't necessary for struct/class/enum definitions
in C++, so avoid the verbosity it adds.
