The VP8 decoder wrapper will request key frames 30 frames after seeing
a packet loss, if it hasn't received a state refresh (only possible
through key frames in this version).
For this to be possible the jitter buffer has been made aware of
picture ids to be able to detect frame losses. Legacy JB code to
handle streams without marker bits was also removed since it
conflicts with streams with FEC.

1. Updated code to set _lastdecodedSeqNum after clean up of old frames (2/3 instances were updated, 1 was ok).
2. Updated _lastDecodedSeqNum based on empty packets that arrive after the frame which they belong to was already decoded (as was with existing code with regard to filler packets).
B. Code clean up.
