Before this change, there was no way for a client to indicate to the dcSCTP library if a packet that was supposed to be sent, was actually sent. It was assumed that it always was. To handle temporary failures better, such as retrying to send packets that failed to be sent when the send buffer was full, this information is propagated to the library. Note that this change only covers the API and adaptations to clients. The actual implementation to make use of this information is done as a follow-up change.
