discovery/gossiper test: define unknown node announcement as stal
To mimic the current behaviour of the router's IsStaleNode, we make the
mockGraphSource consider a unknown node with no channels in the graph as
stale.

discovery/gossiper_test: modify TestProcessAnnouncement to process node
ann last

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.

discovery: ensure we only broadcast NodeAnnouncements of public nodes
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.

discovery/gossiper: don't return on errChan for ChannelUpdate not yet processed
Previosuly we would immediately return nil on the error channel for
premature ChannelUpdates, which would break the expection that a a
returned non-error meant the update was successfully added to the
database. This meant that the caller would believe the update was added
to the database, while it is actually still in volatile memory and can
be lost during restarts.

This change makes us handle premature ChannelUpdates as we handle other
premature announcements within the gossiper, by deferring sending on the
error channel until we have reprocessed the update.

discovery: avoid always validating ECDSA sigs by asking router if item is fresh
In this commit, we reduce the amount of unnecessary work that the
gossiper can carry out. When CPU profiling some nodes, I noticed that
we’d spend a lot of time validating the signatures for an announcement,
only to realize that the router already had it.

To remedy this, we’ll use the new methods added to the channel router
in order to avoid unnecessarily validating an announcement that is
actually stale. This should reduce memory usage (since it uses big
int’s under the scenes), and also idle CPU usage.

b74a281b57 discovery test: test for remote ChannelUpdate for unknown channel
This commit adds a test that ensures that if we receive a
ChannelUpdate for a channel we don't know about, it will
be reprocessed after we receive a ChannelAnnouncement for
that channel.

discovery: use lnwire.ChanUpdateFlag masks when examinig ChannelUpdate msgs
In this commit, we now properly examine the Flag field within the
ChannelUpdate message as a bitfield. Before this commit we would
manually check the flags for zero or one. This was incorrect as a their
bit has now been defined. To properly dispatch the messages, we’ll now
treat it properly as a bitmask.

918ef2808f gossiper_test: add tests for deDupedAnnouncements struct
Add tests for new deDupedAnnouncements struct in gossiper_test.
Test the various functionalities of the struct - that empty
struct contains no announcements, that announcements of each type
can be added and properly de-duplicated, that the batch of
announcements is delivered correctly, and that after reset the
struct again contains no announcements.
