Rusty Russell 112115022c gossmap: don't crash if we see a duplicate channel_announce.
Apparently we had two private channel announcements (the !private assert
failed).  While this shouldn't happen, don't crash because of it.

Fixes: #5578
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: Plugins: topology plugin could crash when it sees duplicate private channel announcements.

Alex Myers 4167fe8dd9 gossip_store: fix offset error
The gossip_store version byte was unaccounted for in the initial traversal
of gossip_store_end. This lead to an offset and a bogus message length
field. As a result, an early portion of the gossip_store could have been
skipped, potentially leading to gossip propagation issues downstream.

Fixes #5572 #5565

Changelog-fixed: proper gossip_store operation may resolve some previous gossip propagation issues

niftynei 30aa1d79fb bkpr: for zerconfs, we still wanna know you're opening a channel
We need a record of the channel account before you start sending
payments through it. Normally we don't start allowing payments to be
sent until after the channel has locked in but zeroconf does away with
this assumption.

Instead we push out a "channel_proposed" event, which should only show
up for zeroconfs.

niftynei 0617690981 coin_mvt/bkpr: add "stealable" tag to stealable outputs
If we expect further events for an onchain output (because we can steal
it away from the 'external'/rightful owner), we mark them.

This prevents us from marking a channel as 'onchain-resolved' before
all events that we're interested in have actually hit the chain.

Case that this matters:
Peer publishes a (cheating) unilateral close and a timeout htlc (which
we can steal).
We then steal the timeout htlc.

W/o the stealable flag, we'd have marked the channel as resolved when
the peer published the timeout htlc, which is incorrect as we're still
waiting for the resolution of that timeout htlc (b/c we *can* steal it).

niftynei a45da63280 bkpr: pass the node_id over for channel_opens, add to account
it's nice to know what node your channel was opened with. in theory we
could use listpeers to merge the data after the fact, except that
channels disappear after they've been closed for a bit. it's better to
just save the info.

we print it out in `listbalances`, as that's a great place account level
information

niftynei a3d82d5a01 bkpr: exclude non-wallet events in the balance snapshot
Anchor outputs are ignored by the clightning wallet, but we keep track
of them in the bookkeeper. This causes problems when we do the balance
checks on restart w/ the balance_snapshot -- it results in us printing
out a journal_entry to 'get rid of' the anchors that the clightning node
doesnt know about.

Instead, we mark some outputs as 'ignored' and exclude these from our
account balance sums when we're comparing to the clightning snapshot.

Rusty Russell eff53495db lightningd: make "is peer connected" a tristate.
First, connectd tells us the peer has connected, and we call the connected hook,
and if it says it's fine, we are actually connected and we fire off notifications.

Of course, we could be disconnected while in the connected hook, and that would
mean we tell people about a connection which is no longer current.

Make this clear with a tristate: if we're not marked disconnected by
the time the hooks finish, we're good.  It also gives us a cleaner
"connect" command return when we connected but disconnected before
processing.

Rusty Russell c3efba16ff JSON: don't print deprecated amount fields any more
A small change in one routine creates a lot of changes!  We actually
recommended moving away from these in v0.7.0 (2019-02-28), but never
deprecated them formally.

Changelog-Deprecated: JSON-RPC: `pay`, `decode`, `decodepay`, `getroute`, `listinvoices`, `listpays` and `listsendpays` `msatoshi` fields (use `amount_msat`).
Changelog-Deprecated: JSON-RPC: `getinfo` `msatoshi_fees_collected` field (use `fees_collected_msat`).
Changelog-Deprecated: JSON-RPC: `listpeers` `channels`: `msatoshi_to_us`, `msatoshi_to_us_min`, `msatoshi_to_us_max`, `msatoshi_total`, `dust_limit_satoshis`, `our_channel_reserve_satoshis`, `their_channel_reserve_satoshis`, `spendable_msatoshi`, `receivable_msatoshi`, `in_msatoshi_offered`, `in_msatoshi_fulfilled`, `out_msatoshi_offered`, `out_msatoshi_fulfilled`, `max_htlc_value_in_flight_msat` and `htlc_minimum_msat` (use `to_us_msat`, `min_to_us_msat`, `max_to_us_msat`, `total_msat`, `dust_limit_msat`, `our_reserve_msat`, `their_reserve_msat`, `spendable_msat`, `receivable_msat`, `in_offered_msat`, `in_fulfilled_msat`, `out_offered_msat`, `out_fulfilled_msat`, `max_total_htlc_in_msat` and `minimum_htlc_in_msat`).
Changelog-Deprecated: JSON-RPC: `listinvoices` and `pay` `msatoshi_received` and `msatoshi_sent` (use `amount_received_msat`, `amount_sent_msat`)
Changelog-Deprecated: JSON-RPC: `listpays` and `listsendpays` `msatoshi_sent` (use `amount_sent_msat`)
Changelog-Deprecated: JSON-RPC: `listforwards` `in_msatoshi`, `out_msatoshi` and `fee` (use `in_msat`, `out_msat` and `fee_msat`)
Changelog-Deprecated: JSON-RPC: `listfunds` `outputs` `value` (use `amount_msat`)

Rusty Russell a52bdeee01 common: add msat to sat convert helper.
We don't always want to round down, sometimes we want to fail.
