We do this a lot, and had boutique helpers in various places. So add
a more generic one; for convenience it returns a pointer to the new
end element.
I prefer the name tal_arr_expand to tal_arr_append, since it's up to
the caller to populate the new array entry.

It's an array: we were only saving the single element; if there was more than
one changed HTLC we'd get a bad signature!
The report in #1907 is probably caused by the other side re-requesting
something we considered already finalized; to avoid this particular error,
we should set the field to NULL if there's no last_sent_commit.
I'm increasingly of the opinion we want to just save all the update
packets to the db and blast them out, instead of doing this
second-guessing dance.

This means we don't try to unilaterally close after a restart, *and*
we can tell onchaind to try to use the point to recover funds when the
peer unilaterally closes.

We're currently overriding fatal() with something that actually
returns, which contrasts with its declaration as NORETURN.
This breaks in the next patch which wants a real fatal() in wallet.h.

In several places we use low-level tal functions because we want the
label to be something other than the default. ccan/tal is adding
tal_*_label so replace them and shim it for now.

tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

I would have liked to make it a tal object, then we'd catch most
things with our memleak detection. However, sqlite3 doesn't seem to
allow allocator overrides.

The no-rescan change requires us to rescan one last time from the first_blocknum
of our channels (if we have any). The migrations just drop blocks that are
higher, then insert a dummy with the first_blocknum, and then clean up after
us. If we don't have any channels we don't go back at all.

These transactions being seen on the blockchain triggered some action in
onchaind so we need to replay them when we restore the onchaind.

Currently these are either transactions we sent ourselves or transactions that
we are watching because they are part of a channel.

So we know how much counterparty could theoretically steal from us
(msatoshi_to_us - msatoshi_to_us_min) and how much we could
theoretically steal from counterparty (msatoshi_to_us_max -
msatoshi_to_us).
For more piloting goodness.
This may be causing #1280, since with `--daemon` the DB is being reopened
without enabling the foreign key relations and hence the delete cascades.

It would be better to give them unique values, but we don't fully support
db migrate anyway and this is simple (though they will end up using the
same key for multiple channel closes if created before this commit).
Note that even if bip32_max_index is currently unset, it defaults to 0
so it will be found.

The billboard is now far more useful to tell what's going on, and this
gets us closer to a state == owner mapping.

And now we can finally do the db upgrade to remove any OPENINGD

We use it on the secrets array for the moment, but it's also useful
for remote_shutdown_scriptpubkey, as used in the next patch.

We usually did this, but sometimes they were named after what they did,
rather than what they cleaned up.
There are still a few exceptions:
1. I didn't bother creating destroy_xxx wrappers for htable routines
which already existed.
2. Sometimes destructors really are used for side-effects (eg. to simply
mark that something was freed): these are clearer with boutique names.
3. Generally destructors are static, but they don't need to be: in some
cases we attach a destructor then remove it later, or only attach
to *some* cases. These are best with qualifiers in the destroy_<type>
name.

We need these to decode any returned errors.
We remove it from struct pay_command too, and load directly from db
when we need it.
