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

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.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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.

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.
Allow a function as well as (or instead of!) an sql statement. That
will let us do things like set per-channel values to the global
defaults, for example.
Since we remove the NULL termination, the final entry is ARRAY_SIZE()-1
not ARRAY_SIZE()-2.

More efficient to measure the ARRAY_SIZE(), which is a runtime
constant. We move it into the unit test.

Below this code appears:
if (current != orig)
db_exec(__func__, db,
"INSERT INTO db_upgrades VALUES (%i, '%s');",
orig, version());
But since the loop pre-increments current, this is always true. I wondered
why there were so many duplicates in my db_upgrades table!

This field was used by `pay` to hold the bolt11 description if the bolt11
string used `h` to hash the description (which nobody ever did). If the
`h` field wasn't present, it could contain anything, as it wasn't checked.
It's really useful to have a label for payments (eg. '1 Cuban'), but adding
yet-another option would be painful, so we simply rename 'description'
to 'label' except inside the db.
This means we need to do some tricky parameter parsing to handle array
and keyword JSON arguments, but only until we remove the old name.

Without this, there's no proof of payment, since it is the signed invoice
that make the receipt valid.

In particular this matches the case of `their_unilateral/to_us` outputs, which
were missing their addresses so far.

In order to avoid having to ask the HSM for public keys to
their_unilateral/to_us outputs we just store the `scriptPubkey` with the UTXO,
which can then be converted to the P2WPKH address.

We want to disallow using unconfirmed outputs by default, so making the
default 1 confirmation seems a good idea. This also matches `bitcoind`s
minimum confirmation requirement.
Arming however breaks some of our tests, so I used `minconf=0` for the
breaking tests and added a new test specifically for the `minconf` parameter
for `fundchannel`.

This allows us to specify that an output must have been confirmed before the
given maximum height. This allows us to specify a minimum number of
confirmations for an output to be selected.
