The newly introduced type is used to determine what the call semantics of the
hook are. We have `single` corresponding to the old behavior, as well as
`chain` which allows multiple plugins to register for the hook, and they are
then called sequentially (if all plugins return `{"result": "continue"}`) or
exit the chain if the hook event was handled.
This is currently in opening_control since that's the only part that has
access to the uncommitted_channel internals. Otherwise it's independent from
the specific daemon.
These messages may be exchanged between the master and any daemon. For now
these are just the daemons that a peer may be attached to at any time since
the first example of this is the custommsg infrastructure.
Add "peer not connected" and "unknown peer" as error codes, so that
users can check against numeric error codes instead of textual error
messages.

Takes advantage of upfront-shutdown-script to permit users to
specify the close-to address for a channel at open, by adding
a `close_to` field to `fundchannel_start`.
Note that this only is in effect if `fundchannel_start` returns
with `close_to` set -- otherwise, peer doesn't
support `option_upfront_shutdown_script`.
This is mainly an internal-only change, especially since we don't
offer any globalfeatures.
However, LND (as of next release) will offer global features, and also
expect option_static_remotekey to be a *global* feature. So we send
our (merged) feature bitset as both global and local in init, and fold
those bitsets together when we get an init msg.

Big wiring re-org for funding-continue
In openingd, we move the 'persistent' state (their basepoints,
pubkey, and the minimum_depth requirement for the opening tx) into
the state object. We also look to keep code-reuse between
'continue' and normal 'fundchannel' as high as possible. Both
of these call the same 'fundchannel_reply' at the end.
In opening_control.c, we remap fundchannel_reply such that it is
now aware of the difference between an external/internally funded
channel open. It's the same return path, with the difference that
one finishes making and broadcasting the funding transaction; the
other is skips this.
Add an RPC method (not working at the moment) called
`fundchannel_continue` that takes as its parameters a
node_id and a txid for a transaction (that ostensibly has an output
for a channel)
Some channels won't be opened with a wtx struct, so keep
the total funding amount separate from it so we can
show some stats for listpeers.
Note that we're going to need to update/confirm this once
the transaction gets confirmed.
For the `fundchannel_cancel` we're going to want
to 'successfully' fail a funding channel operation. This allows
us to report it a failure back as an RPC success, instead of
automatically failing the RPC request.
We're going to need this for P2WSH scripts. pull it out into
a common file plus adopt the sanity checks so that it will allow for
either P2WSH or P2WPKH (previously only encoded P2WPKH scripts)
"result" should always be an object (so that we can add new fields),
so make that implicit in json_stream_success.
This makes our primitives well-formed: we previously used NULL as our
fieldname when calling the first json_object_start, which is a hack
since we're actually in an object and the fieldname is 'result' (which
was already written by json_object_start).
There were only two cases which didn't do this:
1. dev-memdump returned an array. No API guarantees on this.
2. shutdown returned a string.
I temporarily made shutdown return an empty object, which shouldn't
break anything, but I want to fix that later anyway.

This new parameter takes a list of outpoints (as txid:vout) and fund a channel from the corresponding utxos.

We currently allocate utxos off cmd, but the next commit will persist a
wtx beyond the command which created it, breaking that assumption.
In general, a struct member should be owned by the struct itself, and
a tal context should be an explicit arg, not implicit.

- result fundchannel command now depends on successful or failed broadcast of the funding tx
- failure returns error code FUNDING_BROADCAST_FAIL
- don't fail the channel when broadcast failed, but keep in CHANNELD_AWAITING_LOCKIN
- after fixing the initial broadcast failure, the user could manually rebroadcast the tx and
keep the channel
openingd/opening_funder_finished:
- broadcast_tx callback function now handles both success and failure
jsonrpc: added error code FUNDING_BROADCAST_FAIL
manpage: added error code returned by fundchannel command
This makes the user more aware of broadcast failure, so it hopefully doesn't
try to broadcast new tx's that depend on its change_outputs. Some users have reported (see
issue #2171) a whole sequence of fundings failing, because each funding was using the change
output of the previous one, which would not confirm.
This causes a compiler warning if we don't do something with the
result (hopefully return immediately!).
We use was_pending() to ignore the result in the case where we
complete a command in a callback (thus really do want to ignore
the result).

in json_getroute with a bad seed value.

Prior to this, lightningd would hand uninteresting peers back to connectd,
which would then return it to lightningd if it sent a non-gossip msg,
or if lightningd asked it to release the peer.
Now connectd hands the peer to lightningd once we've done the init
handshake, which hands it off to openingd.
This is a deep structural change, so we do the minimum here and cleanup
in the following patches.
Lightningd:
1. Remove peer_nongossip handling from connect_control and peer_control.
2. Remove list of outstanding fundchannel command; it was only needed to
find the race between us asking connectd to release the peer and it
reconnecting.
3. We can no longer tell if the remote end has started trying to fund a
channel (until it has succeeded): it's very transitory anyway so not
worth fixing.
4. We now always have a struct peer, and allocate an uncommitted_channel
for it, though it may never be used if neither end funds a channel.
5. We start funding on messages for openingd: we can get a funder_reply
or a fundee, or an error in response to our request to fund a channel.
so we handle all of them.
6. A new peer_start_openingd() is called after connectd hands us a peer.
7. json_fund_channel just looks through local peers; there are none
hidden in connectd any more.
8. We sometimes start a new openingd just to send an error message.
Openingd:
1. We always have information we need to accept them funding a channel (in
the init message).
2. We have to listen for three fds: peer, gossip and master, so we opencode
the poll.
3. We have an explicit message to start trying to fund a channel.
4. We can be told to send a message in our init message.
Testing:
1. We don't handle some things gracefully yet, so two tests are disabled.
2. 'hand_back_peer .*: now local again' from connectd is no longer a message,
openingd says 'Handed peer, entering loop' once its managing it.
3. peer['state'] used to be set to 'GOSSIPING' (otherwise this field doesn't
exist; 'state' is now per-channel. It doesn't exist at all now.
4. Some tests now need to turn on IO logging in openingd, not connectd.
5. There's a gap between connecting on one node and having connectd on
the peer hand over the connection to openingd. Our tests sometimes
checked getpeers() on the peer, and didn't see anything, so line_graph
needed updating.

openingd calculates our reserve based on the channel amount (even if
we're funding, to keep the calculation in one place), but it wasn't

New codes: FUND_MAX_EXCEEDED, FUND_CANNOT_AFFORD, FUND_DUST_LIMIT_UNMET.
The error message "Cannot afford fee" was not exactly correct because
it would also occur if the amount requested could not be afforded. So
I changed it to the more generic "Cannot afford transaction".
Other things:
* Fixed off-by-one satoshi in fundchannel manpage.
* Changed 'arror' to 'error' because we are not pirates.
Until now, `command_fail()` reported an error code of -1 for all uses.
This PR adds an `int code` parameter to `command_fail()`, requiring the
caller to explicitly include the error code.
This is part of #1464.
The majority of the calls are used during parameter validation and
their error code is now JSONRPC2_INVALID_PARAMS.
The rest of the calls report an error code of LIGHTNINGD, which I defined to
-1 in `jsonrpc_errors.h`. The intention here is that as we improve our error
reporting, all occurenaces of LIGHTNINGD will go away and we can eventually
remove it.
I also converted calls to `command_fail_detailed()` that took a `NULL` `data`
parameter to use the new `command_fail()`.
The only difference from an end user perspecive is that bad input errors that
used to be -1 will now be -32602 (JSONRPC2_INVALID_PARAMS).
Because we have too many which are never used and I don't want to document
them.
1. Remove unused anchor_onchain_wait. When implemented, it should be
hardcoded to 100 or more.
2. Remove anchor_confirms_max. 10 always reasonable, and we can readd
an override option should someone need it.
3. max_htlc_expiry should be the same as locktime_max (which increases
from 3 to 5 days by default): they're both a limit on how long
funds can be locked up.
4. channel_update_interval should always be a dev option.
