Subject: Sorry in this just befor code freeze commit. This is fix to
 usr.sbin/trpt and tcp_debug.[ch] I think of putting this after 4.0 but,,,

 -There was bug that when INET6 is defined,
  IPv4 socket is not traced by trpt.

 -I received request from a person who distribute a program
  which use tcp_debug interface and print performance statistics,
  that
    -leave comptibility with old program as much as possible
    -use same interface with other OSes

  So, I talked with itojun, and synced API with netbsd IPv6 extension.

makeworld check, kernel build check(includes GENERIC) is done.

But if there happen to any problem, please let me know and
I soon backout this change.
