* Returns the RoadBits on an arbitrary tile

* - road tunnels: entrance is treated as road piece
* - bridge ramps: start of the ramp is treated as road piece
* - bridge middle parts: bridge itself is ignored
*
* If straight_tunnel_bridge_entrance is set a ROAD_X or ROAD_Y
* for bridge ramps and tunnel entrances is returned depending
* on the orientation of the tunnel or bridge.
* @param tile the tile to get the road bits for
* @param rt the road type to get the road bits form
* @param straight_tunnel_bridge_entrance whether to return straight road bits for tunnels/bridges.
* @return the road bits of the given tile
