This increases the minimum CLTV delta allowed for invoice creation to
provide more headroom above DefaultFinalCltvRejectDelta (19 blocks).
The previous value of 18 was below the reject threshold, which could
allow users to create invoices with CLTV deltas that would be rejected
when receiving payments.
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.
