routing: fail in-flight attempts cleanly on terminal payment failure 
In case of a multi shard payment with more than one in-flight shards,
one shard quitting with a terminal failure will stop the payment
lifecycle and close the `shardHandler`'s `quit` channel. In the
`collectResult` function we're waiting for the `Switch` to
asynchronously return a result for each shard. This may have been
interrupted by the aformentioned `quit` channel's closing skipping
attempt failure (or success) notification towards the control tower
and therefore skipping proper settle/fail info fill in the channel db.
Since payments have a composite state of a global failure reason and
settle/fail info for all attempts, any attempt with an unfilled
settle/fail info keeps a payment in-flight even if the payment itself
isn't in-flight anymore.

routing

Build Status MIT licensed GoDoc

The routing package implements authentication+validation of channel announcements, pruning of the channel graph, path finding within the network, sending outgoing payments into the network and synchronizing new peers to our channel graph state.
