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.
If we kill the daemon without performing any commits we ended up with
a 0 instead of UINT48_MAX which was expected.

And store in peer->last_tx/peer->last_sig like all other places,
that way we broadcast it if we need to.
Note: the removal of tmpctx in funder_channel() is needed because we
use txs[0], which was allocated off tmpctx.

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.
Automatically exiting the DB transaction upon any failure is strange
since it'll kill any later attempt to commit. The commit itself should
be used to verify that everything was ok.
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.
Now we're always sync, just use an fd. Put the hsm_sync_read() helper
here, too, and do HSM init sync which makes things much simpler.

Splitting the detection for outputs that we own into a separate
`wallet_extract_owned_outputs` function and use it when the broadcast
succeeds to re-add the change output back to the database.
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.
Not the nicest code, but it allows us to store the bip32_max_index so
that we don't forget our addresses upon restart. We could have done
the same by retrieving the max index from our index, but then we'd
forget addresses that don't have an associated output. Conversion
to/from string is so that we can store arbitrary one off values in the
DB in the future, independent of type.
