Add datasync, v1messages & disable discovery topic options Adds support for datasync, V1Messages and disabling the discovery topic. This is a backward compatible change as long as they are not toggled on (they are not by default).

Add basic peersyncing 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.
