Log message:
	* Add "is_rib_origin" booleal flag to class RouteEntryOrigin. This
	  flag is set to true if the origin is the RIB.
	
	* Don't redistribute the RIB routes back to the RIB. Otherwise,
	  if we are exporting routes from a protocol X with worse admin
	  distance into RIP, we may end-up with oscillation: if an exported
	  route is added again to RIB as a RIP route, the original route
	  from protocol X won't be a winner anymore, and the RIB will withdraw it
	  from RIP. If the RIP propagates the withdraw back to RIB, then the
	  original route from protocol X will again become a winner, the RIB
	  will add it again to RIP and so on.
