dijkstra: fix heap ordering.
We were always ordering heap by distance, not score (which are different if we are routing by cheapest, not shortest!). This simplifies our callbacks, too. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> |

common/dijkstra: routine to calculate shortest/cheapest path.
The user supplies callbacks to do channel selection and comparison. Note that this continues to map the entire network; not just to the source, for use with random routing.
