This commit modifies the graph topology test to
properly count channel updates and node
announcments in the event that they are batched
into a single topology update. The prior logic
made the assumption that they were always in
distinct topology updates, so this method should
be more general and robust.
In this commit, we open an additional channel between Bob and Carol to
ensure that Bob gets selected as the only routing hint. Previously Bob
would get selected, but with the recent changes, it would no longer
happen due to him not having any advertised edges.
In this commit, we ensure that we don't include routing hints for
unadvertised nodes at the time of invoice creation. Otherwise, this
would lead us to leak these unadvertised nodes to anyone who can get
their hands on the invoice being created. To prevent this, we'll now
look at the network graph and ensure that the node in unadvertised if
all of their edges are unadvertised and only extend to us.
In this commit, we filter out nodes who intend to remain private. We do
this to prevent leaking information about them by forwarding their
NodeAnnouncements.
In this commit, we modify the funding manager to send our
NodeAnnouncement to our channel counterparty in the event of an
unadvertised channel. We do this to ensure that our counterparty learns
about some information about us that may aid them in one way or another
(e.g., addresses to reconnect, features supported, etc.).

In this commit, we modify TestProcessAnnouncement to process the node
announcement last. We do this due to the recent change in the gossiper
where we'll only forward node announcements of nodes who intend to
advertised themselves within the network.
This change was needed in order to allow the node announcement to be
broadcast to the greater network, as otherwise the gossiper would assume
the node intends to stay private due to not having any advertised edges.
In this commit, we modify the gossiper to no longer broadcast
NodeAnnouncements of nodes who intend to remain private. We do this to
prevent leaking their information to the greater network.
In this commit, we add a method to the ChannelGraph struct that
determines whether a node is seen as public based on graph's source
node's point of view.
In this commit, we update the genNodeAnnouncement method to also write
an updated version of the node announcment to disk. Before this commit,
we would update the in memory version, but then never write the new
version to disk. As a result, when connecting to new peers, we would
never propagate the new version of this announcement to the network.
