    rtpjitterbuffer: rework packet insert

    Rework the packet queue so that the most common action (insert a packet
    at the tail of the queue) goes very fast.

    Report if a packet was inserted at the head instead of the tail so that
    we can know when to retry _pop or _peek.

If the first received packet is different than the one in seqnum-base, items
will not be popped from the jitter buffer.

seqnum-base is obtained from RTP-Info (in PLAY response). It could be that
RTP-Info contains a different sequence number than the first packet really
received.
