This commit adds basic syncing capabilities with peers if they are both online. It updates the work done on MVDS, but I decided to create the code in status-go instead, since it's very tight to the application (similarly the code that was the inspiration for mvds, bramble, is all tight together at the database level). I reused parts of the protobufs. The flow is: 1) An OFFER message is sent periodically with a bunch of message-ids and group-ids. 2) Anyone can REQUEST some of those messages if not present in their database. 3) The peer will then send over those messages. It's disabled by default, but I am planning to add a way to set up the flags.
