For legacy payments, the hash field will be nil, and we need to use the payment identifier instead. We have multiple ways to fix this: A trivial solution is we can simply call `sharder.GetHash` in `collectResult`, and pass this hash to `attempt.Circuit()`, which ends up multiple methods taking the hash. This is bad as it's confusing why the methods of `HTLCAttempt` need to take another hash value, while itself already has the info via `HTLCAttempt.Hash`. We don't want an exceptional case to influence our main flow. We can then patch the field `HTLCAttempt.Hash`, and set it to the payment hash if it's nil, which can be done in `collectResult`. This is also less optimal as it means every htlc attempts, either legacy or not, now need to bear this context. The best way to do this is to patch the field in `reloadInflightAttempts`. As we are sure any new payments made won't be legacy, and the only source of legacy payments comes from reloading existing payments.
routing
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.
