fed3bf503e keep track of which packets were sent as retransmissions 
When an ACK for a packet that was retransmitted arrives, we don't need
to retransmit the retransmission, even if it was lost.

2d64953e0e remove incorrect error check when sending a packet 
There's no need for a check if more than protocol.MaxTrackedSentPackets
packets were sent. There are certain situations where we allow (via
SendingAllowed()) sending of more packets, and we shouldn't throw an
error when the session then actually sends these packets.

fbeba1f73a make sure that at least every 20th ACK is retransmittable 
This is important because we need to make sure that we can remove old
ACK ranges from the received packet history. The logic we implemented
before was not correct, since we only made sure that every 20th packet
would be retransmittable, but we didn't have any guarantee that this
packet would also contain an ACK frame.

9ef3a47da5 send multiple packets at once, if the pacing delay is very small 
This is an optimization to avoid waking of the run loop every couple of
microseconds.

9b3139a1d6 use the packet receive time in the receivedPacketHandler 
By passing the packet receive time to the receivedPacketHandler we can
get rid of two time.Now() syscalls.

8e8892b064 remove the SentFin method from the stream 
When a FIN is dequeued from the stream by the streamFramer, it is
guaranteed to be sent out. There's no need to explicitely signal that to
the stream.

085624be20 replace stream.LenOfDataForWriting by HasDataForWriting 
The return value (the length of data for writing) was only used to
determine if the stream has data for writing. Therefore it's easier to
just return a bool.

No functional change expected.

daff6256b9 don't negotiate the maximum incoming streams value 
The maximum number of incoming streams doesn't need to be negotiated. It
is a value that is only announced by the peer, and has to be respected.
Furthermore, Chrome doesn't seem to care about the MSPC value anymore
(since MIDS was introduced), so there's no need to send this in the
handshake any more.

0e1a8a5f8c move the max flow control increments out of the params negotiator 
The params negotiator was just keeping track of the value set in the
quic.Config. The max flow control increments are not subject to
negotiation, but an independent implementation decision of every peer.
