connectd is going to end up using this do demux; make it fast and complete.
Fixing this reveals a problem in openingd: it now extracts the channel_id
from funding_signed (which is where we transition off the temporary), and
gets upset. So fix that.

1. Freeing an unconfirmed channel already releases the subd, so don't
do that explicitly.
2. Use channel->owner to transfer ownership where possible, using
channel_set_owner() which handles all the cases.
This simplifies the code and makes it more readable, IMHO.

Fire off a snapshot of current account balances (node wallet + every
'active' channel) after we've caught up to the chain tip for the *first*
time (in other words, on start).
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.
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.
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.
Get rid of the 'movement_idx', since we replay events now.
Since we're removing a field from the 'coin_movement' event emission, we
bump the version type.
Changelog-Updated: `coin_movements` events have been revamped and are now on version 2.
we used this originally to suppress duplicate issuance of coin-move
events; we're assuming that any plugin expects duplicate events though
(and knows how to de-dupe them), so we no longer need this logic.
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.
we assume that every event coming from onchaind is for that channel's
account, but now that we sometimes track external + wallet events from
onchaind, we should only add the channel account name if there's nothing
set there already
We're not going to do 'spend tracks' any more; instead we'll emit an
event whenever an output is included in a broadcast tx
(even if the broadcast fails!!)

Changelog-Changed: Support hsm specific error error code in lightning-cli
The only thing that needs ld->wallet after this is destroy_invoices_waiter (off jsonrpc)
Could not find any other destructors (destroy_*) that need wallet or db access after this.
Any db access would now segfault.
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.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

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
next release.

This is from 6e99c5feaf60cb797507d181fe583224309318e9
We renamed the enctlv field to encrypted_recipient_data in the spec, and the
new onion_message is message 513. We don't handle it until the next patch.
Two renames:
1. blinding_seed -> blinding_point.
2. enctlv -> encrypted_recipient_data.
We don't do a compat cycle for our JSON APIs for these experimental
features only used by our own plugins, we just rename.

since PR #3867 utxos are unreserved by height, destroy_utxos and
related functions are not used anymore so clean them up also
However free(ld->jsonrpc) still needs to happen before free(ld) because its
destructors need list_head pointers from ld
because:
- shutdown_subdaemons can trigger db write, comments in that function say so at least
- resurrecting the main event loop with subdaemons still running is counter productive
in shutting down activity (such as htlc's, hook_calls etc.)
- custom behavior injected by plugins via hooks should be consistent, see test
in previous commmit
IDEA:
in shutdown_plugins, when starting new io_loop:
- A plugin that is still running can return a jsonrpc_request response, this triggers
response_cb, which cannot be handled because subdaemons are gone -> so any response_cb should be blocked/aborted
- jsonrpc is still there, so users (such as plugins) can make new jsonrpc_request's which
cannot be handled because subdaemons are gone -> so new rpc_request should also be blocked
- But we do want to send/receive notifications and log messages (handled in jsonrpc as jsonrpc_notification)
as these do not trigger subdaemon calls or db_write's
Log messages and notifications do not have "id" field, where jsonrpc_request *do* have an "id" field
PLAN (hypothesis):
- hack into plugin_read_json_one OR plugin_response_handle to filter-out json with
an "id" field, this should
block/abandon any jsonrpc_request responses (and new jsonrpc_requests for plugins?)
Q. Can internal (so not via plugin) jsonrpc_requests called in the main io_loop return/revive in
the shutdown io_loop?
A. No. All code under lightningd/ returning command_still_pending depends on either a subdaemon, timer or
plugin. In shutdown loop the subdaemons are dead, timer struct cleared and plugins will be taken
care of (in next commits).
fixup: we can only io_break the main io_loop once
Incase the error handling happening after the quted line is non-critical:
```
return tal_fmt(NULL, "Unable to parse address '%s': %s", arg, err_msg);
```
we should not expand the proposed_listen_announce array without adding
a proposed_wireaddr. So we move the expand of proposed_listen_announce
to the location where we also expand the proposed_wireaddr.
