In preparation for CachedEdgePolicy being used to represent
ChannelEdgePolicy1 or ChannelEdgePolicy2, we update it to have
IsDisabled and HasMaxHTLC booleans (which can be extracted from both
messages) instead of having the MessageFlags and ChannelFlags which only
applies to ChannelEdgePolicy1.
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.
