In this commit, we add a series of methods, and a new database index that we'll use to implement the new discovery.ChannelGraphTimeSeries interface interface. The primary change is that we now maintain two new indexes tracking the last update time for each node, and the last update time for each edge. These two indexes allow us to implement the NodeUpdatesInHorizon and ChanUpdatesInHorizon methods. The remaining methods added simply utilize the existing database indexes to allow us to respond to any peer gossip range queries. A set of new unit tests has been added to exercise the added logic. |

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
