You can now activate dual-funded channels using the
`--experimental-dual-fund` flag
Changelog-Changed: Config: `--experimental-dual-fund` runtime flag will enable dual-funded protocol on this node
We move over to the new "warning" paradigm, instead of using
an "rbf_fail" message.
Every failure is either a warning or an error; on warnings we
hang up and reconnect later, effectively resetting the state.
This takes from the draft spec at https://github.com/lightningnetwork/lightning-rfc/pull/834
Note that if this draft does not get included, the peer will simply
ignore the warning message (we always close the connection afterwards
anyway).

Changelog-Added: Protocol: we now report the new (draft) warning message.
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.

The main change here is that the previously-optional open/accept
fields and reestablish fields are now compulsory (everyone was
including them anyway). In fact, the open/accept is a TLV
because it was actually the same format.
For more details, see lightning-rfc/f068dd0d8dfa5ae75feedd99f269e23be4777381
Changelog-Removed: protocol: support for optioned form of reestablish messages now compulsory.

This means we intercept the peer's gossip_timestamp_filter request
in the per-peer subdaemon itself. The rest of the semantics are fairly
simple however.

Basically we tell it that every field ending in '_msat' is a struct
amount_msat, and 'satoshis' is an amount_sat. The exceptions are
channel_update's fee_base_msat which is a u32, and
final_incorrect_htlc_amount's incoming_htlc_amt which is also a
'struct amount_msat'.

We always hand in "NULL" (which means use tal_len on the msg), except
for two places which do that manually for no good reason.

The next patch includes wire/peer_wire.h and causes a compile error
as lightningd/gossip_control.c defined its own gossip_msg function.
New names are clearer.

Fixes the `short_channel_id` being serialized as 4 bytes block height,
3 bytes transaction index and 1 byte output number, to use 3+3+2 as
the spec says.
The reordering in the unit test structs is mainly to be able to still
use `eq_upto` for tests.
