This is the other origin, besides `bitcoin_tx`, where we create `bitcoin_tx`
instances, so add the context as soon as possible. Sadly I can't weave the
chainparams into the deserialization code since that'd need to change all the
generated wire code as well.

The way we build transactions, serialize them, and compute fees depends on the
chain we are working on, so let's add some context to the transactions.

Since we now have a couple of long-lived dependents it is time we stop
removing channels from the table once they are fully closed, and instead just
mark them as closed. This allows us to keep forwards and transactions foreign
keys intact, and it may help us debug things after the fact.

Instead of deleting the channels we will simple mark them as `CLOSED` from now
on. This is needed for some of the other tables not to end up with dangling
references that would otherwise survive the channel lifetime, e.g., forwards
and transactions.

I was working on rewriting our (somewhat chaotic) tx watching code
for 0.7.2, when I found this bug: we don't always notice the funding
tx in corner cases where more than one block is detected at
once.
This is just the one commit needed to fix the problem: it has some
unnecessary changes, but I'd prefer not to diverge too far from my
cleanup-txwatch branch.

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)
Move it closer to ccan/json_out, in preparation for using that as a
replacement.
In particular:
1. Add a 'quote' field in json_add_member.
2. json_add_member now always escapes if 'quote' is true.
3. json_member_direct is exposed to allow avoiding of escaping.
4. json_add_hex can use this, so no longer needs to be in json_stream.c.
5. We don't make JSON manually, but always use helpers.
6. We now flush the stream (wake reader) only when we close it, or mark
command as pending.

"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.

These are generalized from our internal implementations.
The main difference is that 'struct json_escaped' is now 'struct
json_escape', so we replace that immediately.
The difference between lightningd's json-writing ringbuffer and the
more generic ccan/json_out is that the latter has a better API and
handles escaping transparently if something slips through (though
it does offer direct accessors so you can mess things up yourself!).

This new parameter takes a list of outpoints (as txid:vout) and fund a channel from the corresponding utxos.
Example : fundchannel <id> 10000 normal 1 [10767f0db0e568127fffd7f70a154d4599f42d62babf63230a7c3378bfce3cb0:0, c9e040e0b5fc8c59d5e7834108fbc5583001f414dd83faf0a05cff9d1a92d32c:0]
Take into account the fee we'd have to pay if we're the funder, and
also drop to 0 if the amount is less than the smallest HTLC the peer
will accept.

- 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.
We reserve inputs when we're going to send a transaction, but we don't
unreserve them if we crash. This is most graphically demonstrated by
the txprepare case, which makes it easier to trigger.
Instead, we should query bitcoind to see whether the tx made it out or
not, as we would do manually with dev-rescan-outputs.

We currently allocate utxos off cmd, but the next commit will persist a
wtx beyond the command which created it, breaking that assumption.

a tal context should be an explicit arg, not implicit.

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()'.

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