Outliner: Compile all Outliner files in C++

We want to refactor quite some of the Outliner code using C++, this is a
logical step to help the transition to a new architecture.

Includes plenty of fixes to make this compile without warnings, trying
not to change logic. The usual stuff (casts from `void *`, designated
initializers, compound literals, etc.).
