Two cases:
1. Node no longer has any public channels: remove node_announcement.
2. Node's node_announcement now preceeds all the channel_announcements:
move node_announcement to the end.

This lets detect if a node announce preceeds a channel announce once we
delete the node announcement.

The modern, pytest based, tests now clean up after themselves by removing
directories of successful tests and the base directory if there was no failure.

Compares the `blocknum` in the `short_channel_id` with the range of blocks we
store in the database and abort if we should have known about it. Avoids
bombarding `bitcoind` with requests for channels that have already been spent or
were invalid in the first place.

We *accept* a node_announce if we have a channel_announce, but we
can't queue it until we queue the channel_announce, which we only do
once we have recieved a channel_update.

Previous replies weren't large enough; add another channel and then
use IO tracing to make sure the reply is zlib encoded.

Since we currently only (ab)use it to send everything, we need a way to
generate boutique queries for testing.

We have a function called 'wake_pkt_out' which is really 'start
gossiping', so rename it to 'wake_gossip_out'.
In addition, it's fired both on a timer, and in response to our first
gossip_timestamp_filter, which leads to very confusing (though,
technically, not incorrect) behavior.
Keep a single timer at all times, which now doubles as the flag to
indicating we're syncing right now. Set it once we're done syncing
gossip.
Technically this means we got from once-every-60-seconds to
quiet-for-60-seconds-between-gossip, but that's OK.

And initialize filter (to "never") when we negotiated LOCAL_GOSSIP_QUERIES,
and send initial filter message.

This is kind of orthogonal to the other changes, but makes sense: if we
would instantly or never prune the message, don't accept it.

We use the same system as for gossip: we trickle out replies when we're
otherwise idle.
As we trickle out replies to query_short_channel_ids, we remember the
pubkeys of nodes we mention. At the end, we sort and uniquify, and
then send any node_announcements we have for those.

We use the same system as for gossip: we trickle out replies when we're
otherwise idle.
This is minimal infrastructure: we don't actually process the
query_short_channel_ids message yet, nor do we append node
announcements.

In general, we need to only publish node announcements after
publishing channel announcements, though we can accept node
announcements as soon as we see channel announcements. So we keep a
flag for those node_announcement which haven't been broadcast yet.

handle_pending_cannouncement might not actually add the announcment,
as it could be waiting for a channel_update. We need to wait for
the actual announcement before considering announcing our node.

The gossip-query spec enhancements say not to forward an channel_announcement until
you have receive a channel_update. This test fails for now.

We generate new ones anyway; removing this code changes fixes coming
up which now only need to change one place.

When opening a number channels from a single node we could end up not waiting
for the funding tx to make it into the mempool, instead triggering on a previous
`sendrawtransaction` or `CHANNEL_NORMAL` in the logs. This now checks that the
actual funding transaction makes it into the mempool and that we wait for the
depth change for that specific channel.

We don't have any connection yet, so how could they be active? Disable both
sides to avoid trying to route through them or telling others to use them as
`contact_points` in invoices.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
We're telling gossipd about disconnections anyway, so let's just use that signal
to disable both sides of the channel.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
This was failing some of our integration tests, i.e., the ones closing a channel
and not waiting for sigexchange. The remote node would often not be quick enough
to send us its disabling channel_update, and hence we'd still remember the
incoming direction. That could then be sent out as part of an invoice, and fail
subsequently. So just set both directions to be disabled and let the onchain
spend clean up once it happens.
