show the routing table as exported to the protocol given resp. as returned from its import control hook. To get handling of filtered extended attributes right (even in the old `show route where <filter>' command), the get_route_info hook gets an attribute list and all protocol specific rte attributes are contained there as temporary ones. Updated RIP to do that. Added ea_append() which joins two ea_list's.
