Touches quite a few files because: * Deprecate HEIGHT_V2 because it doesn't contain enough info to be fully useful during sync. Newer peers will re-use BLOCK_SUMMARIES_V2. * For newer peers, instead of sending / broadcasting HEIGHT_V2, send top N block summaries instead, to avoid requests for minor reorgs. * When responding to GET_BLOCK, and we don't actually have the requested block, we currently send an empty BLOCK_SUMMARIES message instead of not responding, which would cause a slow timeout in Synchronizer. This pattern has spread to other network message response code, so now we introduce a generic 'unknown' message type for all these cases. * Remove PeerChainTipData class entirely and re-use BlockSummaryData instead. * Each Peer instance used to hold PeerChainTipData - essentially single latest block summary - but now holds a List of latest block summaries. * PeerChainTipData getter/setter methods modified for compatibility at this point in time. * Repository methods that return BlockSummaryData (or lists of) now try to fully populate them, including newly added block reference field. * Re-worked Peer.canUseCommonBlockData() to be more readable * Cherry-picked patch to Message.fromByteBuffer() to pass an empty, read-only ByteBuffer to subclass fromByteBuffer() methods, instead of null. This allows natural use of BufferUnderflowException if a subclass tries to use read(), or hasRemaining(), etc. from an empty data-payload message. Previously this could have caused an NPE.
