A number of changes to the collect code:
...
* 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.

Significant improvements to the Collect protocol:
...
* Loop detection and untangling. Now uses in-band loop detection that
works.
* Link quality estimation. Now starts with a conservative /
pessimistic estimate for new links.
* Retransmissions. MAC layer and network layer retransmissions are now
decoupled.
* Loss handling. Deals better with losses now.
* Concurrent applications. Each connection now maintains its own
neighbor table with separated cost to sink estimates for each
connection.

Using wherex() to determine the length of the string printed with cputsn() fails if the right edge of the screen was reached as wherex() then returns 0.
...
Therefore we rather count the chars actually printed in cputsn() and return that value thus avoiding usage of wherex() in those scenarios altogether.
