"dissect_ip_tcp_options()" but for options that are like IPv6 options (i.e., the length byte has a value that doesn't include the option code or length byte). Add an "ip_opts.h" header to declare it, and move the declaration of stuff used by it and "dissect_ip_tcp_options()", and the declaration of "dissect_ip_tcp_options()", to that header. Use "dissect_ipv6_options()" for Mobile IPv6 options. Get rid of the unused "mip6_opt_types[]" array in "packet-mip6.h". svn path=/trunk/; revision=8015
