  Modified files:
    sys/sys              filedesc.h 
    sys/kern             kern_descrip.c kern_exec.c kern_fork.c 
  Log:
  Add new function fdunshare() which encapsulates the necessary light magic
  for ensuring that a process' filedesc is not shared with anybody.
  
  Use it in the two places which previously had private implmentations.
  
  This collects all fd_refcnt handling in kern_descrip.c
