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.

Added a way to for specifying lists as parts of structs. These lists

must be initialized with a special LIST_STRUCT_INIT() call before
using.

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.

Allow to exit the process owning the foreground window by pressing ctrl-c. This is especially useful if there's no closebutton on the window frames (or no windows at all).

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.

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.
