8f7f76f8c6 gossipd: don't validate UTXOs on our own channels.
It's an unnecessary round-trip, and can cause us to complain in CI, in
the case where the channel has been closed by the time we ask.

7f5fe52320 gossipd: remove online gossip_store compaction.
It was an obscure dev command, as it never worked reliably.
It would be much easier to re-implement once this is done.

This turned out to reveal a tiny leak on
tests/test_gossip.py::test_gossip_store_load_amount_truncated where we
didn't immedately free chan_ann if it was dangling.

7bdbb62b09 gossipd: remove channel update/annoounce creation and local update handling.
Now lightningd just doesn't tell us about private channels, doesn't
expect us to generate channel gossip, and tells us about public channels
via the addgossip call, we don't need any of this in gossipd.

5583f730de gossipd: always send information about our channels' gossip updates.
Not just when it's a private channel.  This is useful for listpeerchannels in the next patch.
Most of this is renaming.

It also means that source can be NULL, so move it out of the struct and put it in the message,
where it logically belongs, and make it an optional field.

4b4937b9bd gossipd: tell lightningd about all our previous channel_updates at startup.
This will at least *help* the case where these were not populated, causing us
to send errors without channel_updated appended.

It's not perfect: we can still send such errors if the gossip store is
corrupted, and we still send them for private channels, but it should
help.

(The much better fix is far more invasive, so slips to next release!)

532544ce4f gossipd: rename remote_addr to discovered_ip within gossipd
This is cleaner because, the `remote_addr` and `discovered_ip` are
related but two different things.

Within connectd and lightningd we use the peers `remote_addr` feature
to validate (and guess a port) to be used for IP discovery.

Also when a peer reports us a `remote_addr`, this is given to the plugin API
via the `peer_connected` hook. The network port here is not modified for
godd reason! This can be used i.e. to detect if we are behind a NAT.

But once lightningd figures enough peers report the same `remote_addr`,
it sets the port to the selected network and tells gossipd to use that for
`node_announcement` updates.

Hence, within gossipd, there is no (should not be) `remote_addr`.

Changelog-None

67fdc6f8ad gossipd: send updated node_annoucement remote_addr
This is the cheapest algo I came up with that simply checks that the
same `remote_addr` has been report by two different peers. Can be
improved in many ways:

 - Check by connecting to a radonm peers in the network
 - Check for more than two confirmations or a certain fraction
 - ...

Changelog-Added: Send updated node_annoucement when two peers report the same remote_addr.

e7b263304e lightningd: Send updated onion spec messages.
It's very similar to the previous, but there are a few changes:

1. The enctlv fields are numbered differently.
2. The message itself is a different number.

The onionmsg_path type is the same, however, so we keep that constant
at least.

The result is a lot of cut & paste, but we will delete the old one
