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.

ChannelDB: avoid duplicate (host,port) entries in ChannelDB._addresses

after:
node_id -> NetAddress -> timestamp
Look at e.g. add_recent_peer; we only want to store
the last connection time, not all of them.

lnrater: module for node rating
...
Introduces LNRater, which analyzes the Lightning Network graph for
potential nodes to connect to by taking into account channel capacities,
channel open times and fee policies. A score is constructed to assign a
scalar to each node, which is then used to perform a weighted random
sampling of the nodes.

network: load gossip db early
...
The gossip db is loaded early when the network is started to save
time when the gui is locked and a wallet not yet loaded. Side effects
of the LNWallet to start peering when a channel db is loaded is
circumvented.

Improve handling of lightning payment status:

- Move 'handle_error_code_from_failed_htlc' to channel_db,
and call it from pay_to_route, because it should not be
called when HTLCs are forwarded.
- Replace 'payment_received' and 'payment_status'
callbacks with 'invoice_status' and 'request_status'.
- Show payment error logs in the Qt GUI
- In the invoices list, show paid invoices for which
we still have the log.
