lnworker: run create_route_for_payment end-to-end, incl private edges
...
We pass the private edges to lnrouter, and let it find routes end-to-end.
Previously the edge_cost heuristics didn't apply to the private edges
and we were just randomly picking one of the route hints and use that.
So e.g. cheaper private edges were not preferred, but they are now.
PathEdge now stores both start_node and end_node; not just end_node.

Trampoline MPP aggregation:
...
- trampoline node is the final recipient of MPP
- each trampoline receives a bucket of HTLCs
- if a HTLC from a bucket fails, wait for the entire bucket to fail
- move trampoline route and onion code into trampoline module

Reorganize code so that we can send Multi Part Payments:
...
- LNWorker is notified about htlc events and creates payment events.
- LNWorker._pay is a while loop that calls create_routes_from_invoice.
- create_route_from_invoices should decide whether to split the payment,
using graph knowledge and feedback from previous attempts (not in this commit)
- data structures for payment logs are simplified into a single type, HtlcLog

This adds a failing test, where the HTLC switch fulfills an HTLC too soon,
before the corresponding 'update_add_htlc' is irrevocably committed.

Just realised that the "diamond" graph is actually defined in Graph Theory
but it has an extra edge. What we have here is apparently called a "square" graph.
Not that it matters much but might as well name it as such then...
