UDT: Fix close bug. It kept sending ACKs/NAKs even though the underlying socket was already closed. Close #95

UDT: Fix ACK/NAK ddos by implementing a simple rate limiter. It uses a min/max time and doubles the wait time in between.

UDT: Fix critical bugs: congestion window size was not set on senders side; sentAck was not set in case ACK threshold wasn't reached, which caused resendACKTimer to fail to send

UDT: Improve performance by relying on a single ticker instead of creating new ones for ACK/NAK each outgoing packet.
...
Creating new tickers was huge stress for the gc reducing performance (according to pprof 35% was spent on runtime.siftdownTimer).

UDT: Fix critical bugs that appear during high packet loss. Recv: Implement resending ACKs (until ACK2'ed). Send: Implement unsolicited data resending of unacked data packets. Double sending time each try to prevent ddos.

UDT: Remove ackInterval which was never set anyway. Instead, send ACK every few packets depending on congestion window and count of sent packets.
...
Removing LightACK. The implementation of it was confusing (it competed with ACK in a race condition) and rather pointless. LightACKs will be ditched completely to get to a working version.

UDT: Fix ddos in ackEvent. It sets ackTimerEvent which triggers ackEvent ... an endless loop. ackTimerEvent is actually not needed at all.

UDT: Temporary bush fix for buggy code #43 . Packet loss is currently ignored, but at least it works now. The function udtSocketRecv.sendNAK is an endless loop and needs a rewrite.
