Useful for regtest and testnet. Sure, you shouldn't use this on mainnet,
but I haven't restricted it because our users are usually pretty clever.

Changelog-EXPERIMENTAL: BOLT12 offers can now be unsigned, for really short QR codes.
100+ is for experimentation, modern spec practice is to assign feature bits
sequentially as PRs get added, to avoid later renumbering.
Still respect the old bit for now.

And even if we can't find *ourselves* because we have no channels

Changelog-EXPERIMENTAL: JSONRPC: `listoffers` now shows `local_offer_id` when listing all offers.
We were actually using the last commit tx's size, since we were
setting it in lightningd. Instead, hand the min and desired feerates
to closingd, and (as it knows the weight of the closing tx), and have
it start negotiation from there.
This can be significantly less when anchor outputs are enabled: for
example in test_closing.py, the commit tx weight is 1124 Sipa, the
close is 672 Sipa!

Changelog-Changed: Protocol: Use a more accurate fee for mutual close negotiation.
We set amounts to a list, but then don't use the values except
as a boolean.
Make it a boolean, which should also speed the test up!

This lets us transition (with a few supporting changes) to closingd,
which will happily let them mutual close with us.
We already handle the case where this mutual close is redundant (for
packet loss), so this is easy.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: Protocol: We will now reestablish and negotiate mutual close on channels we've already closed (great if peer has lost their database).
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.

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
removing this restriction (only Electrum actually enforced it on

we mark them as requiring mpp.

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).
Temporarily rename old getroute to getrouteold (we will remove this).
Changelog-Changed: JSON-RPC: `getroute` is now implemented in a plugin.

If l2 doesn't have the funding locked in, the rest of the test fails

I did this by copying the updated bech32 code, and then re-patching in
our minor changes:
1. Headers modded (we need size_t)
2. Explicit length for bech32_encode/decode (not 90).
3. Exposing and bech32_ prefix for convert_bits, charset, charset_rev.

Annotating the htlc in `listpeers` with their current status, and
which plugin is currently holding on to them with their
`htlc_accepted` hook can help us debug where plugins may go wrong.
Changelog-Added: jsonrpc: HTLCs in `listpeers` are now annotated with a status if they are waiting on an `htlc_accepted` hook of a plugin.
This test takes 695 seconds, because fundwallet waits for the wallet to
notice the tx, which takes 60 seconds if not DEVELOPER. Do all the waiting
at once, and this speeds the test up to 153 seconds.

result should *always* be an object. This allows it to add fields
without breaking the API. A command which returns "result" as a
string is living in sin.
