Rusty Russell 6115ed02e8 subdaemons: don't stream gossip_store at all.
We now let gossipd do it.

This also means there's nothing left in 'struct per_peer_state' to
send across the wire (the fds are sent separately), so that gets
removed from wire messages too.

Rusty Russell 029d65cf2e connectd: serve gossip_store file for the peer.
We actually intercept the gossip_timestamp_filter, so the gossip_store
mechanism inside the per-peer daemon never kicks off for normal connections.

The gossipwith tool doesn't set OPT_GOSSIP_QUERIES, so it gets both, but
that only effects one place.

As connectd handles more packets itself, or diverts them to/from gossipd,

Rusty Russell 425a7af512 common/coin_mvt: clean up API a little.
1. tal_strndup(.., str, strlen(str)) == tal_strdup()
2. tal_strdup also takes(), so document that.
3. Avoid passing 'struct sha256' on the stack: use ptr.
4. Generally, structures shouldn't keep pointers to things they don't own.
   In this case, mvt->node_id.
5. Make payment_hash a pointer, since NULL is more natural than an all-zero
   hash.

And add NON_NULL_ARGS() to the functions; it's cumbersome, but make it
fairly clear what params are optional.

1. Freeing an unconfirmed channel already releases the subd, so don't

2. Use channel->owner to transfer ownership where possible, using

niftynei 8225a9decf coin_mvt: log events for pushes/lease_fees for leased channels
We need to stash/save the amount of the lease fees on a leased channel,
we do this by re-using the 'push' amount field on channel (which is
technically correct, since we're essentially pushing the fee amount to
the peer).

Also updates a bit of how the pushes are accounted for (pushed to now
has an event; their channel will open at zero but then they'll
immediately register a push event).

Leases fees are treated exactly the same as pushes, except labeled
differently.

Required adding a 'lease_fee' field to the inflights so we keep track of
the fee for the lease until the open happens.

niftynei bddd3694fa coin_mvt: record fees for an outbound htlc
If we initialized the payment, the fees are the entire fee-chain
(final hop amount - starting hop amount)

If it's a payment we routed, the fees are the diff between the
inbound htlc and the outbound (net gain by this routing)

Added to database so data persists nicely.

niftynei 29c6718297 coin_mvt: record new 'fees' field on htlc channel moves
We record the amount of fees collected for a routed payment. For
simplicity's sake on the data agg side, we record the fee payment on
*BOTH* the incoming htlc and the outgoing htlc. Note that this results
in double counting if you add up the fees from both an in-routed and
out-routed payment.

niftynei 8098a4cd21 onchaind: remove 'is_replay' logic
we used this originally to suppress duplicate issuance of coin-move

niftynei d2c4d4aec2 coin_mvts: rewrite how onchain events are recorded, update tests
The old model of coin movements attempted to compute fees etc and log
amounts, not utxos. This is not as robust, as multi-party opens and dual
funded channels make it hard to account for fees etc correctly.

Instead, we move towards a 'utxo' view of the onchain events. Every
event is either the creation or 'destruction' of a utxo. For cases where
the value of the utxo is not (fully) debited/credited to our account, we
also record the output_value. E.g. channel closings spend a utxo who's
entire value we may not own.

Since we're now tracking UTXOs onchain, we can now do more complex
assertions about the onchain footprint of them. The integration tests
have been updated to now use more 'chain aware' assertions about the
ending state.

Jan Sarenik 96f28323bd Set default port according to network
The idea is to have different default ports for different networks.

Current default port is `9735` for everything. Let's use it for
the mainnet and reuse the difference added to the default port
from `rpc_port` values in `bitcoin/chainstate.c`.

Testnet would be `19735` (adding rpc_port - 8332 = `10000`).

Signet would be `39735` (adding rpc_port - 8332 = `30000`).

Regtest would be `19846` (adding rpc_port - 8332 = `10111`).

With Vincenzo's kind pair-programming help over tmate.

Two other commits were squashed into this one so that bisecting
never ends up in half-baked state:

1. chainparams: Fix regtest default rpc_port

   bitcoind -help says this:

    -rpcport=<port>
         Listen for JSON-RPC connections on <port> (default: 8332, testnet:
         18332, signet: 38332, regtest: 18443)

2. test_gossip: Default port for regtest

   hex: 2607 is now .... (could be 4d86 but Elements uses another port)
   dec: 9735 is now any port (could be 19846 ^^ but now is for any port)

   The lines which were binding to default port were removed as the
   default port is different on each network.

NOTE: Remember not to modify gossip_store tests which loads everything raw
      including the checksums.

Changelog-Changed: If the port is unspecified, the default port is chosen according to used network similarly to Bitcoin Core.
