ShutdownInfo contains any info about a previous Shutdown message that we have sent. This commit adds this type along with read and write methods for it in the channel db. The existence of the ShutdownInfo on disk represents the fact that we have previously sent the Shutdown message and hence that we should resend it on re-establish.
channeldb
The channeldb implements the persistent storage engine for lnd and
generically a data storage layer for the required state within the Lightning
Network. The backing storage engine is
boltdb, an embedded pure-go key-value store
based off of LMDB.
The package implements an object-oriented storage model with queries and mutations flowing through a particular object instance rather than the database itself. The storage implemented by the objects includes: open channels, past commitment revocation states, the channel graph which includes authenticated node and channel announcements, outgoing payments, and invoices
