Reduce the number of calls to gettimeofday to lower CPU load. * src/TimeA2.h, src/TimeA2.cc (differenceInMillis): New function. * src/SpeedCalc.h, src/SpeedCalc.cc (calculateSpeed): New function. * src/Peer.h (calculateUploadSpeed): New function. (calculateDownloadSpeed): New function. * src/DefaultPeerStorage.cc (CalculateStat): Added _now variable. In operator(), call Peer::calculateDownloadSpeed(const struct timeval&) and Peer::calculateUploadSpeed(const struct timeval&) Drop connection if no request or piece message is exchanged in a certain interval. * src/DefaultBtInteractive.h (btRuntime): New variable. (inactiveCheckPoint): New variable. (checkActiveInteraction): New function. * src/DefaultBtInteractive.cc (receiveMessages): Reset timer when request or piece message is received. (checkActiveInteraction): New function. (doInteractionProcessing): Call checkActiveInteraction. Fixed the bug that causes remote Metalink and Torrent files are not processed. * src/MultiUrlRequestInfo.cc (createNextRequestInfo): Fixed the bug.
