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.
Changelog-EXPERIMENTAL: Protocol: we can now upgrade old channels to `option_static_remotekey` from https://github.com/lightningnetwork/lightning-rfc/pull/868

Currently we abuse openingd and dualopend to do this, but connectd already
has the ability to talk to peers, so it's more efficient.

Undocumented (caught by json schema!) if we discard channel because it
wasn't open yet, then close returned the empty object. Make it return
a new type in this case.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: JSONRPC: `close` returns `type` "unopened" if it simply discards channel instead of empty object.
Tor v2 hidden services have been deprecated for a while:
https://blog.torproject.org/v2-deprecation-timeline .
This prevents user from being able to set them in the configuration
and to connect to them while still letting us be able to parse them
for gossip.
Changelog-Deprecated: lightningd: v2 Tor addresses. Use v3. See https://blog.torproject.org/v2-deprecation-timeline.

If the peer is offline when we see the funding txid, we don't actually
update the channel's info. Here, we move it up to where the scid is set,
so that we always update the channel's funding_txid to the correct
(mined) information.
We set the timeout on first HTLC, but didn't clear it if that HTLC failed.
It's saner to have a per-HTLC timeout (since that's what it is!) and
also our timer infra is specially coded to scale approximately infinitely so
trying to optimize this is vastly premature.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: Protocol: We would sometimes gratuitously disconnect 30 seconds after an HTLC failed.
1. We don't need to check for NULL before tal_count(NULL).
2. Use of json_for_each_arr iterator is probably better.
3. Weird indent fixed.

Trying to put all the disconnect logic into the same path was a dumb
idea. If you asked to reconnect but passed in an 'unsaved' channel, we
would not call the 'reconnect' code.
Instead, we make a differentiation between "unsaved" channels
(ones that we haven't received commitment tx for) and handle the
disconnect for these separate from where we want to do a reconnect.
We were freeing the payload, which is then subsequently freed by the
plugin_hook caller. Whoops.
Now we pass through to the callback function and just clean up neatly.
