* Added an optional "keep alive" mechanism whereby an idle network is periodically probed by dummy packets to maintain a recent quality metric when there is no traffic. * Bugfix in when new routing metrics should be advertised * Rewrote the ACK logic so that a queuebuf is not allocated for each ack, only for those acks generated by the sink node. * Updated the wrap-around logic for sequence numbers: when a sequence number wraps, it won't go back to 0. Instead, it wraps to 128. This allows us to understand when a node has rebooted: when its seqno is < 128, it has recently rebooted.
