More precise and complete A* performance statistics

Browse source 
Memory usage didn't include path (adp->path), neighbor cache
(adp->neighbor_coords, adp->neighbor_nodes), and the hash table
(adp->hashtab).

While there, print path length.

To get A* statistics on stderr, compile with AS_STATS defined.
