In this commit, we refactor DeleteChannelEdge to use ChannelIDs rather than ChannelPoints. We do this as the only use of DeleteChannelEdge is when we are pruning zombie channels from our graph. When running under a light client, we are unable to obtain the ChannelPoint of each edge due to the expensive operations required to do so. As a stop-gap, we'll resort towards using an edge's ChannelID instead, which is already gossiped between nodes.
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
