niftynei 4dafeede5c coin moves: notify when we make deposits to external accounts
The blockheight is zero though, since these aren't included in a block
yet.

We also don't issue an 'external' deposit event if we can tell that the
address you're sending to actually belongs to our wallet (we'll issue a
deposit event when it gets included in a block)

niftynei ff4ae8b5f4 coin_moves: add an 'originating_account' field
If a coin move concerns an external account, it's really useful to know
which 'internal' account initiated the transfer.

We're about to add a notification for withdrawals, so we can use this to
track wallet pushes to outside addresses

Changelog-Added: JSONRPC: `coin_movement` to 'external' accounts now include an 'originating_account' field

Rusty Russell f6847f44f6 subds: remove "ignore error" from old LND nodes.
This was put in late 2019, and @t-bast says Eclair doesn't ignore their
errors and has had no issues.

It also conflicts with https://github.com/lightning/bolts/pull/932
which suggests you *should* fail when you receive an error.

Rusty Russell 2ab5603624 peer subds: ignore failed writes.
In the case where the peer sends an error (and hangs up) immediately
after init, connectd *doesn't actually read the error* (even after all the
previous fixes so it actually receives the error!).

This is because to tried to first write WIRE_CHANNEL_REESTABLISH, and
that fails, so it never tries to read.  Generally, we should ignore
write failures; we'll find out if the socket is closed when we read
nothing.

Rusty Russell d51fb5207a msg_queue: don't allow magic MSG_PASS_FD message for peers.
msg_queue was originally designed for inter-daemon comms, and so it has
a special mechanism to mark that we're trying to send an fd.  Unfortunately,
a peer could also send such a message, confusing us!

Rusty Russell a93c49ca65 connectd: implement @ correctly.
dev_blackhole_fd was a hack, and doesn't work well now we are async

So, make explicit flags and use them.  This is much easier now we
have all peer comms in one place.

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.

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

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 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.

Rusty Russell 9d18180172 lightningd: really do allow two Torv3 addresses.
This surprised me, since the CHANGELOG for [0.8.2] said:

	We now announce multiple addresses of the same type, if given. ([3609](https://github.com/ElementsProject/lightning/pull/3609))

But it lied!

Rusty Russell 2f247c7bfb torv2: remove support for advertizing and connecting.
October was the date Torv2 is no longer supported by the Tor Project;
it will probably not work at all by next release, so we should remove
it now even though it's not quite the 6 months we prefer for
deprecation cycles.

I still see 110 nodes advertizing Torv2 (vs 10,292 Torv3); we still
parse and display it, we just don't advertize or connect to it.

niftynei b193eb06d3 dusty-htlcs: enforce limit on dusty htlcs
for every new added htlc, check that adding it won't go over our 'dust
budget' (which assumes a slightly higher than current feerate, as this
prevents sudden feerate changes from overshooting our dust budget)

note that if the feerate changes surpass the limits we've set, we
immediately fail the channel.

niftynei 42e40c1ced htlcs: add flag to 'fail immediately'
If we're over the dust limit, we fail it immediatey *after* commiting
it, but we need a way to signal this throughout the lifecycle, so we add
it to htlc_in struct and persist it through to the database.

If it's supposed to be failed, we fail after the commit cycle is
completed.

ZmnSCPxj jxPCSnmZ 5356267f15 *: Use new closefrom module from ccan.
This also inadvertently fixes a latent bug: before this patch, in the
`subd` function in `lightningd/subd.c`, we would close `execfail[1]`
*before* doing an `exec`.
We use an EOF on `execfail[1]` as a signal that `exec` succeeded (the
fd is marked CLOEXEC), and otherwise use it to pump `errno` to the
parent.
The intent is that this fd should be kept open until `exec`, at which
point CLOEXEC triggers and close that fd and sends the EOF, *or* if
`exec` fails we can send the `errno` to the parent process vua that
pipe-end.

However, in the previous version, we end up closing that fd *before*
reaching `exec`, either in the loop which `dup2`s passed-in fds (by
overwriting `execfail[1]` with a `dup2`) or in the "close everything"
loop, which does not guard against `execfail[1]`, only
`dev_disconnect_fd`.

ZmnSCPxj jxPCSnmZ 20fe5c6ab1 common/json.c: Have `json_add_literal` *use* `len` argument.
The current `json_add_literal` does not use its `len` argument, at all:

09c2fef4a4/common/json.c (L1076-L1083)

Which is something of a WTF, why even require the `len` argument if it
is not even used in the function?
This would have been acceptable if it were a callback and the
callback-requiring function passed it in always, but this function is
not intended to be a callback but instead to be called directly.

Existing callers always pass in `strlen(literal)`, so this bug was not
noticed before:

09c2fef4a4/lightningd/jsonrpc.c (L511)
