Several locations in the code (notably `ai_info` and `waypoint_h`) previously stored pointers for waypoints and waypoint lists that need to be valid for more than one frame. Since both waypoint lists and waypoint paths may change size, resulting in vector reallocation, the information should be stored as indexes instead. Fixes scp-fs2open#6353.
