	bgp           route_table_ribin.cc 

Log message:
	Add an explicit check at the beginning of
	RibInTable<A>::push_next_changed_nexthop() whether there are any
	nexthops to push.
	
	This fixes a coredump problem if we are exporting, say, static routes
	and we disconnect and reconnect the network cable 2+ times
	(waiting long enough after each disconnection/connection for XORP
	to notice it).
	Typically, after the second disconnection bgp would coredump,
	because of a race condition: push_next_changed_nexthop() has
	been scheduled after 0ms, but before it is executed the
	policy_redist4/0.1/delete_route4 XRL is received, and its processing
	invalidates the _current_chain iterator (and the corresponding
	_nexthop_push_active flag).
