Create a C string (which the caller needs to free) with the executed commands
in this session.
The detour via the callback allows us to not make the corelib depend on the

In the future we might want to use undo-commands for mobile as
well (even if not implementing undo).
Therefore, move the undo-command source from desktop-widgets
to their own commands top-level folder.
