Log message:
	Changes related to fixing policy-related race condition when
	BGP might start and leak routes before the policy configuration
	has been received.
	
	The high level idea is that the policy manager will always
	send push_routes XRL to BGP even if there is no policy
	configuration.
	Then, on the BGP side the BGP processing will start only after it
	has received push_routes XRL from the policy manager.
	
	This change here is the part that makes sure that the policy manager
	will always send a push_routes XRL to BGP even if there is
	no policy configuration.
	
	Note that BGP depends on the policy manager (as defined in the rtrmgr
	template files), hence the policy manager will always be running
	before BGP has started.
	
	The details of the changes are:
	* Move all the BGP-related add_varmap policy XRLs inside the
	  bgp template block.
	  Thus, the policy manager will be properly configured even
	  if the "policy {}" configuration block is empty.
	
	* Always send an export or an import BGP policy statement to the
	  policy manager even if the policy statement is empty.
	
	This change is needed for Bugzilla entry #698
