hla: Rework toplevel HLA classes.

Better seperation between the rti and the hla level
of classes. Decouple object model setup from the
need to connect at a federate. Fix alignment computations
for the standard hla data types. Work towards an
interaction class abstraction. Add more flexibility in
deriving from the base classes and adding callbacks.
