	* bgp_advertise.c : (baa_hash_alloc, baa_hash_key, baa_hash_cmp)
	  conforms to quagga hash API. Defines _hash_[alloc|key|cmp] with
	  void * arguments as defined by the API.
	* bgp_aspath.c,h : (aspath_key_make) conforms to quagga hash API.
	  Defines _hash_[alloc|key|cmp] with void * arguments as defined by
	  the API.
	* bgp_attr.c,h : (cluster_hash_alloc, cluster_hash_key_make,
	  cluster_hash_cmp, transit_hash_alloc, transit_hash_key_make,
	  transit_hash_cmp, attrhash_key_make, attrhash_cmp,
	  bgp_attr_hash_alloc) conforms to quagga hash API. Defines
	  _hash_[alloc|key|cmp] with void * arguments as defined by the API.
