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()'.
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.

Instead of lightningd telling us when it's ready, we ask it.
This also provides an opportunity to have a plugin hook at this point.

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.
These are always handed to subdaemons as a set, so group them. This makes
it easier to add an fd (in the next patch).

The chainparams are needed to know the prefixes, so instead of passing down
the testnet, we pass the entire params struct.

68fe5eacde introduced a skip in the iteration
of the available funds, which means utxos[i] may be off the end of utxos.

The old value of 1000 sat was too small to cover the dust reserves.
This lead to the situation when trying to open a channel with minimal
amount, the channels got refused because they were not able cover the
commitment fees.
For this reason the minimal capacity should be increased to i.e. 10k
satoshi, as the technical minimum that also accounts for fees and
reserves is somewhere around 6k sat.
This fixes block parsing on testnet; specifically, non-standard tx versions.
We hit a type bug in libwally (wallt_get_secp_context()) which I had to
work around for the moment, and the updated libsecp adds an optional hash
function arg to the ECDH function.
Fixes: #2563

We're going to make it async, so start by moving the core code into
invoice.c and having that directly call fail/success functions for the
htlc.
We add an extra check in fulfill_htlc() that the HTLC state is correct:
that can't happen now, but may once we're async.

We'd like to display the receive and resolution times in the forwardings
table. In order to remember the receive time we need to store it in the DB
along with the other information.

I tried to just do gossipd, but it was uncontainable, so this ended up being
a complete sweep.
We didn't get much space saving in gossipd, even though we should save
24 bytes per node.

Node ids are pubkeys, but we only use them as pubkeys for routing and checking
gossip messages. So we're packing and unpacking them constantly, and wasting
some space and time.
This introduces a new type, explicitly the SEC1 compressed encoding
(33 bytes). We ensure its validity when we load from the db, or get it
from JSON. We still use 'struct pubkey' for peer messages, which checks
validity.

Pubkeys are not not actually DER encoding, but Pieter Wuille corrected
me: it's SEC 1 documented encoding.

- add config value min_capacity_sat that will replaces the magic value
min_effective_htlc_capacity = AMOUNT_MSAT(1000000)
- add config switch min_capacity_sat
wallet/test/run-wallet was failing the valgrind check; turns out
`sqlite3_expanded_sql` expects you to manage the memory of strings
it returns. from `sqlite3.h`:
** ^The string returned by sqlite3_expanded_sql(P), on the other hand,
** is obtained from [sqlite3_malloc()] and must be free by the application
** by passing it to [sqlite3_free()].
Adding a giant IO message simply causes it to be pruned immediately,
so truncate it if it's more than 1/64 the max size.

I was tempted to create a new db_select_stmt wrapper type, but that means
a lot of boilerplate around binding, which expects to work with db_prepare
*and* db_select_prepare.
This lets us clearly differentiate between db queries (which don't need to
go to a plugin) and db changes (which do).

1. Rename channel_funding_locked to channel_funding_depth in
channeld/channel_wire.csv.
2. Add minimum_depth in struct channel in common/initial_channel.h and
change corresponding init function: new_initial_channel().
3. Add confirmation_needed in struct peer in channeld/channeld.c.
4. Rename channel_tell_funding_locked to channel_tell_depth.
5. Call channel_tell_depth even if depth < minimum, and still call
lockin_complete in channel_tell_depth, iff depth > minimum_depth.
6. channeld ignore the channel_funding_depth unless its >
minimum_depth(except to update billboard, and set
peer->confirmation_needed = minimum_depth - depth).
- Intrduce DB update `channel` values: `feerate_base` and `feerate_ppm`
- Make fist use of now context realted DB migration
- Add `struct channel` members of the same name
- Use struct values instead of config when commiting new channels
This will add the testnet config copyNpaste to test_utils.c,
so that the test stups can set these.
Alternatively, to reduce code duplication, we can move the
testnet_config and mainnet_config from options.c to options.h.
