Log message:
	If the routing computation causes a change in the internal routing
	table then updated routes need to be sent to the RIB, either as
	add,delete or replace routes. The add, delete and replace route
	methods are also an entry point for generating or removing summary
	information from other areas. Replace route is implemented as a call
	to delete route followed by a call to add route, this works fine for
	sending routes to tbe RIB but is causing a problem with summary
	generation. A replace operation is currently causing a summary LSA to be
	deleted then a new summary LSA to be added back, although the deleted LSA
	is correctly set to MaxAge and withdrawn and then a new LSA is
	generated, it is generated with the same original sequence number it
	would be more efficient and less ambiguous if there was an explicit
	summary replace operation.
	
	This current change has added an argument to the add and delete
	operations to determine whether a call should be made to the summary
	code. The replace operation will still call delete followed by add but
	will not call summary delete followed by summary add.
