Note that we don't actually need the output number: it's the tx itself
which is confirmed. And the next caller doesn't have it convenient, so
eliminate it.

These are not confirmed by the normal methods (wallet_can_spend is false!),
so we'll deal with them manually.
We use UTXO_FIELDS in wallet_add_utxo, too, for consistency.

This seems like a premature optimization: it tried to cut down the number of
allocations by reusing the same `struct invoice_details` while iterating through
a number of results. But this sidesteps the checks by `valgrind` and we'd miss a
missing field that was set by the previous iteration.

Well, it's generated by shachain, so technically it is a sha256, but
that's an internal detail. It's a secret.

Simplification of the offset calculation to use the rescan parameter, and rename
of `wallet_first_blocknum`. We now use either relative rescan from our last
known location, or absolute if a negative rescan was given. It's all handled in
a single location (except the case in which the blockcount is below our
precomputed offset), so this should reduce surprises.

This will be used to replay transactions that were witnessed in the blockchain
during startup, so that onchaind can be recreate its state.

The only use for these was to compute their txids so we could notify depth
in case of reorgs.

This fixes the root cause of https://github.com/ElementsProject/lightning/issues/1212
where we deleted the payment because we wanted to retry, then retry failed
so we had an (old) HTLC without a matching payment. We then fed that
HTLC to onchaind, which tells us it's missing, and we try to fail the
payment and deref a NULL pointer.

Will be used later to filter out outputs we are interested in, and
trigger db updates with them.

In preparation for removing in-memory invoice objects.
Since they will be removed, there will no longer be any
individual invoice objects to attach to.
Since we create new entries from wallet_channel_insert(), there's no
need for the branches. And indeed, many wallet functions can be
static.

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.

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.

With fallback depending on chainparams: this means the first upgrade
will be slow, but after that it'll be fast.

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.
