Added a timer to each phase structure that keeps track of for how long
...
a particular receiver has not ACKed packets. After some time
(currently 16 seconds), the sender will begin sending full strobe
periods again.

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.

Rewrite of important parts of the Collect logic: link estimation
...
calculation and parent selection. This fixes a severe bug that caused
loops when packets were erroneously retransmitted due to ACK loss.
