912f877482 Pass node features through to RouteHops 
This exposes the latest Init-context features in the ChannelDetails
passed to the Router during route calculation, which combines those
with the Node-context features tracked from node_announcements to
provide the latest Node-context features in RouteHop structs.

Fields are also added for Channel-context features, though those are
only partially used since no such features are defined today anyway.

These will be useful when determining whether to use new
TLV-formatted onion hop datas when generating onions for peers.

fd1d5fd62c Randomize initial onion packet data. 
This avoids at least the trivial hop count discovery attack, though
other obvious ones remain and are slightly harder to avoid.
