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 solves a couple of issues with the need to synchronously drop the
connection in case we were required to understand what the peer was talking
about while still allowing users to experiment, just not kill connections.
We cannot let users use `sendcustommsg` to inject messages that are handled
internally since it could result in our internal state tracking being borked.
This command injects a custom message into the encrypted transport stream to
the peer, allowing users to build custom protocols on top of c-lightning
without requiring any changes to c-lightning itself.
This is needed to fully implement handling of blockheight disagreements
between us and payee.
If payee believes the blockheight is higher than ours, then `pay`
should wait for our node to achieve that blockheight.

This is the final step: we pass the complete fee_states to and from

If a 'upfront_shutdown_script' was specified, show the address +

Changelog-added: JSON API: `listpeers` channels now include `close_to` and `close_to_addr` iff a `close_to` address was specified at channel open
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.

This patch adds a channel_id parameter to allow for specifying
channels that are lacking a short_channel_id.
Useful in the case where a peer has 1) multiple channels (ONCHAIN etc)
and 2) a channel where the funding transaction hasn't been
broadcast/mined.
Command format: close id [unilateraltimeout] [destination]
Close the channel with peer {id}, forcing a unilateral
close after {unilateraltimeout} seconds if non-zero, and
the to-local output will be sent to {destination}. If
{destination} isn't specified, the default is the address
of lightningd.
Also change the pylightning:
update the `close` API to support `destination` parameter
Currently the only source for amount_asset is the value getter on a tx output,
and we don't hand it too far around (mainly ignoring it if it isn't the
chain's main currency). Eventually we could bubble them up to the wallet, use
them to select outputs or actually support assets in the channels.
Since we don't hand them around too widely I thought it was ok for them to be
pass-by-value rather than having to allocate them and pass them around by
reference. They're just 41 bytes currently so the overhead should be ok.

`close` takes two optional arguments: `force` and `timeout`.
`timeout` doesn't timeout the close (there's no way to do that), just
the JSON call. `force` (default `false`) if set, means we unilaterally
close at the timeout, instead of just failing.
Timing out JSON calls is generally deprecated: that's the job of the
client. And the semantics of this are confusing, even to me! A
better API is a timeout which, if non-zero, is the time at which we
give up and unilaterally close.
The transition code is awkward, but we'll manage for the three
releases until we can remove it.
The new defaults are to unilaterally close after 48 hours.

- Related Changes for `warning` notification
Add a `bool` type parameter in `log_()` and `lov()`, this `bool` flag
indicates if we should call `warning` notifier.
1) The process of copying `log_book` of every peer to the `log_book` of
`ld` is usually included in `log_()` and `lov()`, and it may lead to
repeated `warning` notification. So a `bool`, which explicitly indicates
if the `warning` notification is disabled during this call, is necessary
.
2) The `LOG_INFO` and `LOG_DEBUG` level don't need to call
warning, so set that `bool` paramater as `FALSE` for these log level and
only set it as `TRUE` for `LOG_UNUAUSL`/`LOG_BROKEN`. As for `LOG_IO`,
it use `log_io()` to log, so we needn't think about notifier for it.
Keeping the uintmap ordering all the broadcastable messages is expensive:
130MB for the million-channels project. But now we delete obsolete entries
from the store, we can have the per-peer daemons simply read that sequentially
and stream the gossip itself.
This is the most primitive version, where all gossip is streamed;
successive patches will bring back proper handling of timestamp filtering
and initial_routing_sync.
We add a gossip_state field to track what's happening with our gossip
streaming: it's initialized in gossipd, and currently always set, but
once we handle timestamps the per-peer daemon may do it when the first
filter is sent.

A new string field is added to the command structure and is specified at the creation of each native command, and in the JSON created by 'json_add_help_command()'.
Keep watching and updating scid until ANNOUNCE_MIN_DEPTH, even when channel is private.
When scid changes, we fail channeld so it will restart and initialize with updated
scid and add it to rtable. Reorgs can change funding tx's height/index after lockin,
which could happen with small minimum_depth=1.
New fields don't have to be spelled out twice.
The raw version are called _only, so we don't miss a call
accidentally. We can rename them when we finally deprecated old
fields.

The original idea is to "tal" channel on the "ctx"(In fact, we'd like to set ctx as "ld").

1. amount operations should force you to check validity, rather than
needing a separate call, so make amount_msat_to_u32 return bool,

we now only need that one amount call, but also 'check' will correctly

When in this state, we send a canned error "Awaiting unilateral close".
We enter this both when we drop to chain, and when we're trying to get
them to drop to chain due to option_data_loss_protect.
As this state (unlike channel errors) is saved to the database, it means
we will *never* talk to a peer again in this state, so they can't
confuse us.
Since we set this state in channel_fail_permanent() (which is the only
place we call drop_to_chain for a unilateral close), we don't need to
save to the db: channel_set_state() does that for us.
This state change has a subtle effect: we return WIRE_UNKNOWN_NEXT_PEER
