  Modified:    sys/kern  kern_prot.c
  Log:
  Fully implement the clause in Appendix B.4.2.2 from Posix 1003.1
  that allows traditional BSD setuid/setgid behavior.
  
  The only visible difference should be that a non-root setuid program
  (eg: inn's "rnews" program) that is setuid to news, can completely
  "become" uid news. (ie: setuid(geteuid())  This was allowed in
  traditional 4.2/4.3BSD and is now "blessed" by Posix as a special
  case of "appropriate privilige".
  
  Also, be much more careful with the P_SUGID flag so that we can use it
  for issetugid() - only set it if something changed.
