ISIS_ROUTE_FLAG_ACTIVE flag before running SPF.
* isisd.[ch]: Separate route tables for different levels. SPF is done
separately, but in case of L1L2 area they have to be merged.
* isis_zebra.c: Set/unset ISIS_ROUTE_FLAG_ZEBRA_SYNC flag correctly in
case of adding/removing IPv4 routes.
* zebra_route.c: Rework route validating process. Merging L1 and L2
tables in case of L1L2 area.
In short - many changes to make SPF work more correctly, add/remove
to/from RIB also works now. It's still very far from perfect though.
