commit 3a912d3f6ec53b907fe7f8f1b1f494807f2b468d

    mgcp: Align the code closer to Annex A and introduce bad_seq
    
    Introduce the bad_seq handling that is dealing with a very
    long sequence number jump. The only missing part is the
    probation handling that is of not that much interest right
    now.
    
    Change the initialization sequence, in case of a new SSRC
    re-set the jitter and transit time calculation to an initial
    value. The sender might be a different system that takes a
    different path so the average jitter does not make that
    munch sense.

    mgcp: Change order and types of varriables to follow the Annex

    mgcp: Move the max_seq assignment into each branch
    
    The initialization would put max_seq to seq - 1 while init_seq
    of the annex does not. Move the max_seq assignment into all the
    branches.

commit 2d7298182db8ce8ed84749c89e82f412cacda60f
Author: Holger Hans Peter Freyther <holger at moiji-mobile.com>

    mgcp: Make the packet loss calculation per session
    
    Somehow we end up with calculations of 65536 for the packet loss
    that is RTP_SEQ_MOD. So there might have been a sequence overflow
    but no packets to count against it. I have no idea how this can
    happen and could not reproduce it. But when we change the SSRC
    we should re-initialize the state. Separate the total packets and
    octets from the packets we count per SSRC.
