Prep-work patch for congestion-control
This patch addresses the missing field in various data-structures to track valuable information to implement the congestion-control algorithms and manage sub-connections states. It adds the possibility to queue up to 2 SACKs chunks when the connection is not gapping. At the same time, it pushes some variable/field renaming for better readibility.
