We were double counting channel lease fees because we were double firing
the channel open event sequence (so to speak). If we don't report
balances for unopened channels, we don't have this problem?

Be more graceful in shutting down: this should fix the issue where
bookkeeper gets upset that its commands are rejected during shutdown,
and generally make things more graceful.
1. Stop any new RPC connections.
2. Stop any per-peer daemons (channeld, etc).
3. Shut down plugins.
4. Stop all existing RPC connections.

6. Free up peer, chanen HTLC datastructures.
7. Close database.

Changelog-Added: Protocol: private channels will only route using short-channel-ids if channel opened with option_scid_alias-supporting peer.
We *should* remember the channel type, since this is only required
if they set the channel_type to include option_scid_alias.
However, since we support channel upgrade, channel_type really needs
a new table. I have a patch for that, from my abandoned original
"fastopen" branch for aliases, but it's too big a chance for rc2 IMHO.
Meanwhile, we allow exposeprivatechannels's scids to be either real or
the aliases.

First, how we record "our_funds" and then apply pushes vs lease_fees
(for liquidity ad buys/sales) was exactly opposite.
For pushes we were reporting the total funded into the channel, with the
push representing how much we'd later moved to the peer.
For lease_fees we were rerporting the total in the channel, with the
push representing how much was already moved to the peer.
We fix this (from a view perspective) by re-adding lease fees to what's
reported in the channel funding totals. Since this is now new behavior
(for leased channel values), we added new fields so we can take the old
field names thru a deprecation cycle.
We also make it possible to differentiate btw a push and a lease_fee
(before they were all the same), by adding to new fields to `listpeers`:
`fee_paid_msat` and `fee_rcvd_msat`.
This allows us to avoid math in the bookkeeper, instead we just pick
the numbers out directly and record them.
Fixes#5472
Changelog-Added: JSON-RPC: `listpeers` now has a few new fields for `funding` (`remote_funds_msat`, `local_funds_msat`, `fee_paid_msat`, `fee_rcvd_msat`).
Changelog-Deprecated: JSON-RPC: `listpeers`.`funded` fields `local_msat` and `remote_msat` are now deprecated.
9cad7d6a6a changed the behavior of `channel_active`, which slightly
broke how our balance snapshots work (we need info about channels that
aren't on-chain yet).
This patches adds AWAITING_UNILATERAL back in.
We used to tell connectd to remember our connect delay, and hand it
back (increased if necessary).
Instead, simply record when we last tried to connect. If it was less
than 10 minutes ago, double delay (up to 5 minutes max), otherwise
reset delay to 1 second.
This covers all scenarios: whether we reconnect then immediately
disconnect, or never successfully connect, it doesn't matter.

Fixes: #5453
We need a record of the channel account before you start sending
payments through it. Normally we don't start allowing payments to be
sent until after the channel has locked in but zeroconf does away with
this assumption.
Instead we push out a "channel_proposed" event, which should only show
up for zeroconfs.
If we expect further events for an onchain output (because we can steal
it away from the 'external'/rightful owner), we mark them.
This prevents us from marking a channel as 'onchain-resolved' before
all events that we're interested in have actually hit the chain.
Case that this matters:
Peer publishes a (cheating) unilateral close and a timeout htlc (which
we can steal).
We then steal the timeout htlc.
W/o the stealable flag, we'd have marked the channel as resolved when
the peer published the timeout htlc, which is incorrect as we're still
waiting for the resolution of that timeout htlc (b/c we *can* steal it).
it's nice to know what node your channel was opened with. in theory we
could use listpeers to merge the data after the fact, except that
channels disappear after they've been closed for a bit. it's better to
just save the info.
we print it out in `listbalances`, as that's a great place account level
information
We don't push out a coin_move for a channel open until it's locked in,
but this causes problems for channels that close before they're locked.
So if we go the "close before locked in" route, we push out a channel
open event.
These will get a blockheight of 0, if we haven't seen the
funding transaction in a block yet.

ERROR tests/test_gossip.py::test_announce_dns_without_port - ValueError:
I wondered how `tests/plugins/dblog.py` worked, since it is supposed to fail

```
@plugin.init()

But it was set to "null". That's because 'None' in python is turned into a literal
JSON "null", and we take that as the default value.
We also cleanup the popt->description double-assignment (a leftover
from when this was optional).

We were waiting too long for the reconnect to happen (60s default),
which caused this test to timeout.
When testing, let's speed up the reconnect.
L2 tried to reconnect but didn't have connection information in its
gossip -- is there a way to ask/save connection data from a node you're
making a channel with that doesn't rely on their node_announcement?

The only places which should call try_reconnect now are the "connect"
command, and the disconnect path when it decides there's still an
active channel.
This introduces one subtlety: if we disconnect when there's no active
channel, but then the subd makes one, we have to catch that case!
This temporarily reverts "slow" reconnections to fast ones: see next
patch.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Connectd already does this when we *receive* an error or warning, but
now do it on send. This causes some slight behavior change: we don't
disconnect when we close a channel, for example (our behaviour here
has been inconsistent across versions, depending on the code).
When connectd is told to disconnect, it now does so immediately, and
doesn't wait for subds to drain etc. That simplifies the manual
disconnect case, which now cleans up as it would from any other
disconnection when connectd says it's disconnected.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Give them time to process any final messages! If there's a reconnect,
then we need to clean them up immediately of course.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This allows us to detect when lightningd hasn't seen our latest
disconnect/reconnect; in particular, we would hit the following pattern:
1. lightningd says to connect a subd.
2. connectd disconnects and reconnects.
3. connectd reads message, connects subd.
4. lightningd reads disconnect and reconnect, sends msg to connect to subd again.
5. connectd asserts because subd is alreacy connected.
This way connectd can tell if lightningd is talking about the previous
connection, and ignoere it.
