This commit makes the handoff procedure between the breachabiter and
chainwatcher use a function closure to mark the channel pending closed
in the DB. Doing it this way we know that the channel has been markd
pending closed in the DB when ProcessACK returns.
The reason we do this is that we really need a "two-way ACK" to have the
breacharbiter know it can go on with the breach handling. Earlier it
would just send the ACK on the channel and continue. This lead to a race
where breach handling could finish before the chain watcher had marked
the channel pending closed in the database, which again lead to the
breacharbiter failing to mark the channel fully closed.
We saw this causing flakes during itests.
To give users an idea how the new auto-unlock flag can be used in a more
safe way than just writing the password to a file, we add a new wallet
management document and describe the unlock feature in detail.
In automated or unattended setups such as cluster/container
environments, unlocking the wallet through RPC presents a set of
challenges. Usually the password is present as a file somewhere in the
container already anyway so we might also just read it from there.
This commit adds a new "waiting to start" state which may be used to
query if we're still waiting to become the cluster leader. Once leader
we advance the state to "wallet not exist" or "wallet locked" given
wallet availablity.
This commit also changes the order of DB init to be run after the RPC
server is up. This will allow us to later add an RPC endpoint to be used
to query leadership status.
In this commit we add a new error for when we fail to validate the
funding transaction (invalid script, etc) and mark it as a zombie like
the other failed validation cases.
In this commit, we start to add any channels that fail the normal chain
validation to the zombie index. With this change, we'll ensure that we
won't continue to re-process the same set of spent channels over and
over again.
Fixes#5191.
In this commit, we add a new method that allows us to mark a channel as
being a zombie on the fly without needing to go through the normal
channel deletion process.
This ensures the waiting receiving channel always receives an error to
prevent a deadlock when processing a network update that fails due to
the validation barrier.

Since we don't have to worry about network latency within our
integration tests, we can shorten the broadcast timeout for neutrino
integration tests from 5s to 1s.
This commit updates neutrino to the latest version.
This is to deal with on-chain transaction issues, where in certain
situations the transaction wouldn't be broadcasted.
