This supports reestablish on a closed channel: we tell channeld to
respond to the reestablish message appropriately, then close the
channel.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Let the callers do that (only channeld needs to do this).
We temporarily send an error on unknown reestablish in openingd, as
this mimic previous behavior and avoids breaking tests (it does leave
a BROKEN message in the logs though, so
test_funding_external_wallet_corners needs to ignore that for now.

In particular, if one side sees the final CLOSING_SIGNED and the other
doesn't, we won't talk when it reconnects.

It handles all the cases of retransmission, and in the normal case
retransmits shutdown and immediately returns for us to run closingd.
This is actually far simpler and reduces code duplication.

Changelog-Fixed: Protocol: We could get stuck on signature exchange if we needed to retransmit the final revoke_and_ack.
This was turned by at random by CI:
1. Alice has sent shutdown, but it still waiting for revoke_and_ack.
2. Bob has sent and received shutdown, and sent revoke_and_ack,
so it considers it time for signature exchange.
3. Disconnect before Alice received revoke_and_ack.
4. Reconnect, Bob is in closingd, which doesn't rexmit revoke_and_ack.
5. Timeout.

This allows us to ensure a packet is read by the other end, but we
don't read anything else from them or write anything to them.
Using '+' is similar, but because it closes the connection, the peer
might notice before receiving the packet (such as if it does a write).

Changelog-Fixed: doc: Epic documentation rewrite: each now lists complete and accurate JSON output, tested against testsuite.
1. listpeers has a deprecated `"closer": null`, which we need
to handle in the schema, while trying not to damage our
documentation too much.
2. Don't print a condition if there are no fields to print.
3. Allow a special "untyped" marker for multifundchannel which returns
arbitrary JSON in a field.
4. Allow a single field return (for 'stop').

If we have conditional fields, we often set `additionalProperties` `true`
at the top-level, but then we have to make sure to cover all the possible
combinations in conditionals, so unintended additions don't appear.
This revealed missing fields in delinvoice, for example.

Makes it possible to write a decent JSON schema, but means we need to carry
additional data, so we create a `struct plugin_command`.
We remove the unused struct dynamic_plugin, too.

That's a terrible, terrible idea. (Documentation comes in later patch
which has the schema).
Also, blockheight is a u32, so simplify.

Changelog-Deprecated: JSON-RPC: `listtransactions` `outputs` `satoshis` field (use `msat` instead).
In general, it's better to omit a field than put in a 'null', and
putting variable-named fields in an object is also a bad idea.
This is reflected in how hard this is to express in JSON schema, too.
Others:
1. Remove the obsolete "funding": "LOCAL" from unopened channels, but add
"opener": "local" as used in normal channels.
2. htlc cltv_expiry is a u16.

Changelog-Deprecated: JSON-RPC: `listfunds` `channels` `funding_allocation_msat` and `funding_msat`: use `funding`.

Changelog-Deprecated: JSON-RPC: `listfunds` `channels` `closer` is now omitted if it does not apply, not JSON `null`.
https://github.com/lightningnetwork/lightning-rfc/pull/877 talks about

Changelog-Fixed: Config: `addr` autotor and statictor /torport arguments now advertized correctly.
This mainly helps our CI under valgrind, which starts a fresh instance
and immediately calls the invoice command. This can cause the topology
plugin to try to access the gossmap file before it's created.
We can also move the gossmap reading in topology to init time.

This involves removing some fields from the now-misnamed routing.h
datastructures, and various internal messages.
One non-obvious change is to our "keepalive" logic which refreshes
channels every 13 days: instead of using the 'enabled' flag on the
last channel broadcast to decide whether to refresh it, we use the
local connected status directly.

This turned into a more extensive cleanup than intended. The previous
warnings were overlapping and confusing, especially now MPP is the norm.
*warning_capacity* is now the "even under best circumstances, we don't
have enough incoming capacity", which is really what
warning_mpp_capacity was trying to say (no longer printed).
*warning_offline* and *warning_deadends* are only given if adding such
peers would have helped give capacity (i.e. not if *warning_capacity*
is set). The new *warning_private_unused* tells you that we would
have sufficient capacity, but we refused to expose private channels.
The test cases have been enhanced to cover the new warnings.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: JSON-RPC: `invoice` now gives `warning_private_unused` if unused unannounced channels could have provided sufficient capacity.
Changelog-Changed: JSON-RPC: `invoice` warnings are now better defined, and `warning_mpp_capacity` is no longer included (since `warning_capacity` covers that).
Invoices need to know what the peers' update contains, to create
routehints. It also wants to know if a peer has no other public
channels (so-called "dead end" peers) to eliminate them from routehint
consideration.
This was previously done by a special function to ask gossipd.
