We don't actually process onion messages here any more (they moved to
connectd), but the flag and object files were still linked.

Changelog-Added: Protocol: We now set the `dont_forward` bit on private channel_update's message_flags (as per latest BOLTs).
This contains the zeroconf stuff, with funding_locked renamed to
channel_ready. I change that everywhere, and try to fix up the
comments.
Also the `alias` field is called `short_channel_id`.

Changelog-Changed: Protocol: `funding_locked` is now called `channel_ready` as per latest BOLTs.
We don't need to hand it to channeld: it will read it! We simply
need to tell it to expect it.
Similarly, openingd/dualopend will never see it, so remove that logic.

Suggested by @m-schmook, I realized that if we append it later I'll
never get it right: I expect parameters min and max, not max and min!

Changelog-Added: Protocol: you can now alter the `htlc_minimum_msat` and `htlc_maximum_msat` your node advertizes.
We used to calculate it ourselves. Unfortunately this needs to
be done in several places, since new_channel() isn't used to fully
create a channel in the case of dual funding :(

We now let gossipd do it.
This also means there's nothing left in 'struct per_peer_state' to
send across the wire (the fds are sent separately), so that gets
removed from wire messages too.

It's probably not worth fixing for the other daemons.
Changelog-Changed: JSON-RPC: `ping` now only works if we have a channel with the peer.

This supports reestablish on a closed channel: we tell channeld to
respond to the reestablish message appropriately, then close the
channel.

We don't actually set desired_type yet, but this handles it.
Changelog-EXPERIMENTAL: Protocol: we can now upgrade old channels to `option_static_remotekey` from https://github.com/lightningnetwork/lightning-rfc/pull/868

We used this for dual funded opens, to track the receipt of signatures.
We're moving all of this over to dualopend now, however, so we no longer
need the PSBT in channeld.
The previous onion_message code required a confirmed, not-shutting-down
channel, not just a connection. That's overkill; plus before widespread
adoption we will want to connect directly as a last resort.

Required to determine if this msg used expected reply path.
Also remove FIXME (om->enctlv is handled above).

Prior to this patch update, we expected a client to call
`openchannel_signed` before checking for peer's tx-sigs messages on the
wire.
When moving to a 'multifundchannel' approach, we'll need to be able to
collect sigs from our peers before sending our tx_sigs message. There's
no strict ordering on when tx-sigs messages are sent/received, so this
is fine.
To do this, we go ahead and start up channeld as soon as
commitment_sigs are secured, so that we process incoming tx-sigs from
our peers as soon as we get them.
We need the PSBT to create the finalized tx from once the peer's
tx_signatures are received. Since we're passing the PSBT, we no longer
need the secondary message to be passed, as it was derived from the
PSBT.
Also removes now unused witness serialization code
v2 of channel establishment, in the accpeter case, now sends 2 messages
to our peer after saving the information to disk (our commitment
signatures and our funding transaction signatures)
v2 channel open uses a different method to derive the channel_id, so now
we save it to the database so that we dont have to remember how to
derive it for each.
includes a migration for existing channels
This means some files get renamed, and I took the opportunity to clarify
our naming (the *d* is important!)
1. channeld/channel_wire.csv -> channeld/channeld_wire.csv
2. channeld/gen_channel_wire.h -> channeld/channeld_wiregen.h
3. enum channel_wire_type -> enum channeld_wire
4. WIRE_CHANNEL_FUNDING_DEPTH -> WIRE_CHANNELD_FUNDING_DEPTH.
