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

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.

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.

Much like the database; peer contains id, address, channel contains
per-channel information. Where we create a channel, we always create
the peer too.
For the moment, peer->log and channel->log coexist side-by-side, to
reduce some of the churn.
Note that this changes the API to dev-forget-channel: if we have more
than one channel, we insist they specify the short-channel-id.

Both when we forget about an opening peer, and at startup. We're
going to be relying on this, and the next patch, as we refactor
peer/channel handling to mirror the db.

This caused a bit of confusion for our testers, when funding a channel
the funds are no longer available and listed in `lisfunds`, causing
them to believe funds to have disappeared. This PR adds funds that are
allocated to channels in the `listfunds` output, together with some
info about the channel, to make sure this doesn't happen again.

These are now logically arrays of pointers. This is much more natural,
and gets rid of the horrible utxo array converters.

Still writing the channel since some of the channel setup parameters
depends on `chan->id` to be set. If we later set the `chan->id`
signatures fail. This prevents OPENINGD channels showing up after
restarting.

We were sideloading it, which is awkward, now it's a field that we can
actually use in the code.

If needed, they should be directly #included; otherwise the following
patches really mess things up.

* Add optional addresstype param to newaddr, which can be one of:
- bech32
- p2sh-segwit
- nothing (defaults to p2sh-segwit)
The naming here mirrors bitcoind
* txfilter already looks for p2wpkh outputs, so we're covered there

This was removed because withdraw-to-self results in more than the

Maintaining it was always fraught, since the command could go away
if the JSON RPC died. Most recently, it was broken again on shutdown
(see below).
In future we may allow pay commands to block on previous payments, so
it won't even be a 1:1 mapping. Generalize it: keep commands in a
simple list and do a lookup when a payment fails/succeeds.

We move it into jsonrpc where it belongs, and make it fail the command.
This means it can tell us exactly what was wrong.

So many channels stuck in channeld_awaiting_lockin, and I don't like
suggesting manually editing the DB, so this adds a very simple way to
sync with bitcoind's UTXO view. `dev` since it is dangerous, then
again if bitcoind says those funds aren't available there's little we
can do anyway.

The previous tests didn't make sense anyway, but I think they were trying
to exclude onchain channels.
We delete completely forgotten channels anyway now, so we don't need
such testing.

Error code is inverted (which makes sense: who returns 'true' on
error?), and anyway there's a leak if we do error.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
`pay_index` has no valid value if not PAID anyway, so
we should correctly leave it uninitialized.
Analysis via valgrind will catch incorrect use of
uninitialized fields.
If we load it with a dummy 0 value, then an
incorrect use of `pay_index` whan invoice is not
PAID will not get caught by valgrind.
