Rusty Russell 12985331f7 htlcs: remove origin_htlc_id from htlc_out.
This is a transient field, so rework things so we don't leave it in
struct htlc_out.  Instead, load htlc_in first and connect htlc_out to
them as we go.

This also changes one place where we use it instead of the am_origin
flag.

Not sure if I got the right syntax for adding an empty blob though!

This triple join should be efficient to read, and to process. We have a

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.

Rusty Russell 220449e1cd ccan: import ccan/json_out and ccan/json_escape.
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!).

Rusty Russell e1dbc0b12b wallet: clean reserved inputs on startup.
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.

Rusty Russell 919f390a93 sendpay: rename 'description' to 'label'.
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.

Rusty Russell c8c3294a23 json-invoice: add routeboost, warnings.
We split json_invoice(), as it now needs to round-trip to the gossipd,
and uniqueness checks need to happen *after* gossipd replies to avoid
a race.

For every candidate channel gossipd gives us, we check that it's in
state NORMAL (not shutting down, not still waiting for lockin), that
it's connected, and that it has capacity.  We then choose one with
probability weighted by excess capacity, so larger channels are more
likely.

As a side effect of this, we can tell if an invoice is unpayble (no
channels have sufficient incoming capacity) or difficuly (no *online*
channels have sufficient capacity), so we add those warnings.

Igor Cota cb6820d445 Do preimage, hash and consequentially bolt11 generation before we store the invoice in db.
This way we store bolt11 to the table as well, in case a client needs it later

Igor Cota 3371168d54 Add bolt11 to the invoice struct.
We store this in case an RPC client asks for it

Rusty Russell 3c0be71d37 wallet: make static, not dynamic decision to insert for everything.
Since we create new entries from wallet_channel_insert(), there's no
need for the branches.  And indeed, many wallet functions can be
static.

Rusty Russell 72108f0cb9 wallet: don't use rowid for the channel's DBID.
We derive the seed from this, so it needs to be unique, but using
rowid forced us to put the channel into the db early, before it
was ready.

Instead, use a counter to ensure uniqueness, initialized when we load
existing peers.  This doesn't need to touch the database at all.

As we now have only two places where the channel is committed (the
funder and fundee paths), so we create a new explicit
'wallet_channel_insert()' function: 'wallet_channel_save()' now just
updates.

Note that this also fixes some weirdness in
wallet_channels_load_active: we strangely avoided loading channels in
CLOSINGD_COMPLETE (which fortunately was a transient state, so
unlikely anyone hit this).  Note that since the lines above already
delete all the OPENINGD channels, we now simply load them all.

Christian Decker b2819f9f97 wallet: Add check that wallet matches the network on startup
Adds a simple check that compares genesis-blockhashes from the
chainparams against the blockhash that the wallet was created
with. The wallet is network specific, so mixing is always a bad idea.

Rusty Russell 6620305606 wallet: use last_processed_block to determine scan start.
With fallback depending on chainparams: this means the first upgrade
will be slow, but after that it'll be fast.

Rusty Russell 6a3ccafaf9 wallet: don't implicitly remove peers, but do it explicitly.
This provides a sanity check that we are in sync, and also keeps the
logic in the program and out of the SQL.

Since the destructor now doesn't clean up the peer, there are some
wider changes to be made when cleaning up.  Most notably we create
lots of channels in run-wallet.c and they previously freed the peer:
now we need free the peer explicitly, so we need to free them first.

Rusty Russell 32411de90e lightningd: split struct peer into struct peer and struct channel.
Much like the database; peer contains id, address, channel contains
per-channel information.  Where we create a channel, we always create
the peer too.

For the moment, peer->log and channel->log coexist side-by-side, to
reduce some of the churn.

Note that this changes the API to dev-forget-channel: if we have more
than one channel, we insist they specify the short-channel-id.
