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.

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

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.

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).

- 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
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.

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 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.

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.

We need to do it in various places, but we shouldn't do it lightly:
the primitives are there to help us get overflow handling correct.

As a side-effect of using amount_msat in gossipd/routing.c, we explicitly
handle overflows and don't need to pre-prune ridiculous-fee channels.

Add the change output to owned_txfilter so its entry in db will
get a confirmation_height when detected in a block by filter_block_txs
before this commit, after a 'withdraw' command, 'listfunds' would
not show our change outputs as confirmed
Modified the log message in wallet_extract_owned_outputs to
append 'CONFIRMED' when it is called with a blockheight arg.
To make distinction between (1st call) when adding owned output to the
db and (2th call) when confirmed in block.
We had a bug 0ba547ee10 caused by
short_channel_id overflow. If we'd caught this, we'd have terminated
the peer instead of crashing, so add appropriate checks.

I upgraded my node with --disable-compat, and a heap of channels closed like:
CHANNELD_NORMAL:We disagree on short_channel_ids: I have 557653x0x1351, you say 557653x2373x1",
This is because the scids are strings in the databases, and it failed to parse
them properly.
Now we'll not start if that happens.

Christian and I both unwittingly used it in form:
*tal_arr_expand(&x) = tal(x, ...)
Since '=' isn't a sequence point, the compiler can (and does!) cache
the value of x, handing it to tal *after* tal_arr_expand() moves it
due to tal_resize().
The new version is somewhat less convenient to use, but doesn't have
this problem, since the assignment is always evaluated after the
resize.

We currently use 'all-zeroes' as 'unknown', but NULL is more natural
even if we have to send it as all-zeroes over the wire due to
expressiveness limitations in our generation code.

This is prep work for when we sign htlc txs with
SIGHASH_SINGLE|SIGHASH_ANYONECANPAY.
We still deal with raw signatures for the htlc txs at the moment, since
we send them like that across the wire, and changing that was simply too
painful (for the moment?).

We always have an addr entry in the db (though it may be an ephemeral socket
the peer connected in from). We don't have to handle a NULL address.
While we're there, simplify new_peer not to take the features args;
the caller who cares immediately updates the features anyway.

If there are two HTLCs with the same preimage, lightningd would always
find the first one. By including the id in the `struct htlc_stub`
it's both faster (normal HTLC lookup) and allows lightningd to detect
that onchaind wants to fail both of them.

The left join should make sure we still get the results but
referencing the fields and/or attempting to write them to the JSON-RPC
result will cause unforeseen problems. So just omit if we forgot
something.
Noted by @cdecker, the term 'local' is grossly overused, and the hout
preimage is basically only used as a sanity check (though I've just put
a FIXME there for now).
Also eliminated spurious blank line which crept into wallet.c.

failoutchannel tells us which channel to send an update for (specifically
for temporary_channel_failure); but we don't save it into the db. It's
not even clear we should, since it's a corner case and the channel might
not even exist when we come back.
So on db restore, change such errors to WIRE_TEMPORARY_NODE_FAILURE
which doesn't need an update.
We also don't memset it to 0 in the normal case (we only access if it
failcode has the UPDATE bit set) so valgrind will trigger if we're
wrong.
