Use packets or packet numbers in algorithms/pseudocode

[martinthomson]

The text for DetectLostPackets claims that acked_packet is a packet number, but the code shows it as having a packet_number field, as well as a time_sent field. Maybe a TimeSent() lookup function would work, but at the level that this code operates, I think that it would be better to talk about packets in the abstract. A real implementation might not carry around all the information a packet might accumulate, but that's for real implementations to worry about.

FWIW, I've fixed this in #304, but only for this specific function. The same problem exists in other functions.
