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.

Don't require ACKs of non-retransmittable packets
...
The way this is implemented here is not particularly nice, but will improve in the future once we implement spurious RTO decection #687 (where we'll need a packetHistory similar to Chrome's). In particular, we don't consider non-retransmittable packets for RTT measurements or for early retransmit. While that might impact performance in some edge cases, it shouldn't be worse than before :)
Fixes #505 .
