This removes duplication of in-memory data during the periodic flushing stage of the mission control store. The existing code entirely duplicates the in-memory cache of the store, which is very wasteful when only a few additional results are being rotated into the store. This has a significant performance penalty specially for wallets that remain online for a long time with a low volume of payments. The worst case scenario are wallets that see at most 1 new payment a second, where the entire in-memory cache is recreated every second. This commit improves the situation by determining what will be the actual changes that need to be committed before initiating the db transaction and only keeping track of these to update the in-memory cache if the db tx is successful.
routing
The routing package implements authentication+validation of channel announcements, pruning of the channel graph, path finding within the network, sending outgoing payments into the network and synchronizing new peers to our channel graph state.
