Rewrite tprintstat() so that netstat -ss functionality works
correctly for the "tp:" case (family iso). To avoid serious code space bloat, stats are now table-driven. A side-effect is that the mbuf chain statistics have been slightly re-ordered to follow the 3 lines of EOT stats (still under Miscellaneous) rather than sandwiched between "dec bits" and the EOTs.
