In this commit, we add a new bit to the existing ChannelType bitfield.
If this bit is set, then it signals that we have the funding transaction
stored on disk. A future change will enable lnd to have the funding
transaction be constructed externally, allowing for things like funding
from a hardware wallet, or a channel created as a sub-branch within an
existing channel factory.
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
