Summary:                    [patch] IPv6: sip_uri_cmp
Description: 
The sip_uri_cmp function separates on two :'s 


/* Strip off "sip:" from the URI. We know this is present
         * because it was checked back in parse_request()
         */
        strsep(&uri1, ":");
        strsep(&uri2, ":");



and then compares hosts with strcmp...

For IP addresses, you need to do a binary comparision. Since there are
many ways to write the same IPv6 address, and there are ways to write IPv4
embedded in IPv6, you need to compare IP addresses here.

The function also strips of header parameters, so
sip:oej at edvina.net;transport=udp and sip:oej at edvina.net;transport=tcp
becomes the same URI, which they are not.
