515f4b3dcd 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.

e44298a9cc Always send retransmissions, irrespective of congestion state 
This should probably only apply to RTOs, but we currently don't have a signal to distinguish them in the queue.

19f627af6f fix NACKing of packets below lowest ACK range in new SentPacketHandler 
This did not cause an error, since the packet didn't exist in the
packetHistory. With this fix, it is more consistent and it saves one
loop iteration.
