Andrea Maria Piana e65760ca85 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.
