We'd like to not keep them in memory and retrieve them on-demand when
`onchaind` is launched. This uses the `channel_htlcs` table as backing
but only fetches the minimal necessary information.

This is a necessary evil since at the time we load `struct htlc_out`
associated with a channel we might not have loaded the `struct
htlc_in` that it depends on, so we defer the rewiring until we have
loaded all HTLCs for all channels. At that point rewiring MUST work,
otherwise we report a failure.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

This is the big one, and it's completely anticlimactic: it loads all
channels that have reached opening and are not marked as
closingd_complete into memory, that's it.

This was supposed to be a temporary solution anyway, and I had a
rather annoying mixup between peer_id and unique_id, the latter of
which is actually a connection identifier.
Definitely not as nice as it could be, but it works for now. This is
primarily intended as a simple dump method that just saves everything
to the database. We will later use smaller incremental updates to
update specific things. wallet_channel_save serves both to insert as
well as update.
This needed a rather annoying hack since sqlite3 can only store
integers up to 2^63, so I just squash it down/invert it, and hope that
we never ever have more than 2^63 updates.
Wallet should really be the container for anything bip32 related, so
I'd like to slowly wean off of `ld->bip32_base` in favor of
`ld->wallet->bip32_base`
We'll re-use them a few times so having them at a central location is
nice. We also fix a bug that was unreserving UTXO entries upon free,
instead of promoting them to being spent.
Since we have a simple way to query the database for UTXOs we can
simplify some of the coin selection logic. That gets rid of the
in-memory list of UTXOs.
