We will have probably failed the others, but either way, don't try to
fulfill an HTLC we've already failed.

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.

And return the correct error message for the channel they give, if
they try to re-establish on an error channel.

Channels are within the peer structure, but the peer is freed only
when the last channel is freed.
We also implement channel_set_owner() and make peer_set_owner() a temporary
wrapper.

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.

This is not connected yet; during the transition, there will be a 1:1
mapping from channel to peer, so we can use channel2peer and peer2channel
to shim between them.

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 avoids clashing with the new_channel we're about to add to lightningd,
and also matches its counterpart new_initial_channel.

We only hand off the peer if we've not started writing, but that was
insufficient: we increment the sn twice on encrypting packet, so there's
a window before we've actually started writing where this is now
wrong.
The simplest fix is only to hand off from master when we've just written,
and have the read-packet path simply wake the write-packet path.

Combining the two was just awkward, so it's clearer to have separate
functions. And we make the lower-level functions do the escaping.

For the impatient! First time users following these steps may get an error like "Unable to locate package libsodium-dev" if apt-get update is not run first.
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.
