niftynei ff069ff924 rbf: consolidate failure paths, use "warnings"
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.

Rusty Russell a7c5a1f1d2 lightningd: implement receiving warnings.
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.

Rusty Russell 9d57612415 gossipd, channeld: handle onion messages in gossipd so we don't need a channel.
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.

Rusty Russell 93d04d08d0 wire: update to latest version of the spec.
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.

Rusty Russell 728bb4e662 common/gossip_store: handle timestamp filtering.
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.

Rusty Russell 28f5da7b2f tools/generate-wire: use amount_msat / amount_sat for peer protocol.
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'.

Christian Decker 05e951d748 wire: Correct the short channel id serialization to use 3+3+2
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.
