Juliusz Chroboczek 9b1d814b58 Rework packetcache loss statistics. 
Don't maintain loss, which is too error-prone.  Instead, maintain
expected and received packet counts, and compute loss from that.

Juliusz Chroboczek f0cf9ae141 Fix loss statistics on NACK. 
Since we don't use a separate RTX SSID, we must explicitly account for
NACKed packets in our loss statistics.

Juliusz Chroboczek 86f7594626 Discard old keyframes. 
Avoids seqno wraparound.  Unlikely, but I'm supersticious.
