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.

Fixes: #1806
Changelog-Added: config: `force_feerates` option to allow overriding feerate estimates (mainly for regtest).
We don't do it for sendinvoice (yet?).

Changelog-EXPERIMENTAL: `fetchinvoice` can take a payer note, and `listinvoice` will show the payer_notes received.
We don't support it (yet), but update the spec to include it.
We include the previous field (recurrence_signature) as a shim for the
moment, for compat with existing nodes. It's ugly, but next release
we'll stop *sending* it, then finally we'll stop accepting it!

Changelog-Fixed: JSONRPC: `listinvoice` no longer crashes if given an invalid (or bolt12) `invstring` argument.
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.
Show amount they were trying to pay with, not invoice amount.
Also, show min fee in closing, not fee they offered.

Incoming HTLCs are rejected by the HTLC logic if the payload contains
an even type that `lightningd` doesn't recognize. This is to prevent
us from accidentally accepting a payment that has extra semantics
attached (for example if we get a keysend payment and don't know what
to do with the TLV field containing the message we should reject it,
otherwise the overall semantics of the message delivery fail).
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.

Changelog-Added: Protocol: We will now reestablish and negotiate mutual close on channels we've already closed (great if peer has lost their database).
This supports reestablish on a closed channel: we tell channeld to
respond to the reestablish message appropriately, then close the
channel.

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.

1. Hide the now-deprecated enable-autotor-v2-mode option.
2. Really don't print dev- options.
3. Don't print true and false as strings in some cases.

Changelog-Fixed: JSON-RPC: `listconfigs` would list some boolean options as strings `"true"` or `"false"` instead of using JSON booleans.
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.

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` `last_tx_fee`: use `last_tx_fee_msat`.
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
receive), so start by allowing creation of giant invoices, though
we mark them as requiring mpp.
Changelog-Changed: JSON-RPC: `invoice` now allows creation of giant invoices (>= 2^32 msat)

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

Prior to this, sending a v1 address (or, in fact, any random crap!)
would cause the unsupporting node to unilaterally close.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
An "active" channel may still be CHANNELD_AWAITING_LOCKIN, so have ->scid NULL.
You can only trigger this by trying to sendpay to the node using a
manual route, since routing would never use such a channel.

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.
We don't actually set desired_type yet, but this handles it.
