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 .

accept duplicate and delayed packets
...
We used to reject duplicate and packets with packet numbers lower than
the LeastUnacked we received in a STOP_WAITING frame, because we didn't
accept overlapping stream data. For all other frames, duplicates never
were an issue. Now that we accept overlapping stream data, there's no
need to reject those packets, in fact, processing a delayed packet will
be beneficial for performance.
