    Fix a problem where chan_sip would ignore "old" but valid responses.

    chan_sip has had a problem for quite a long time that would manifest when
    Asterisk would send multiple SIP responses on the same dialog before receiving
    a response. The problem occurred because chan_sip only kept track of the highest
    outgoing sequence number used on the dialog. If Asterisk sent two requests out,
    and a response arrived for the first request sent, then Asterisk would ignore
    the response. The result was that Asterisk would continue retransmitting the
    requests and ignoring the responses until the maximum number of retransmissions
    had been reached.

    The fix here is to rearrange the code a bit so that instead of simply comparing
    the sequence number of the response to our latest outgoing sequence number, we
    walk our list of outstanding packets and determine if there is a match. If there is,
    we continue. If not, then we ignore the response.

    In doing this, I found a few completely useless variables that I have now removed.
