  Modified files:
    sys/kern             kern_descrip.c 
    sys/sys              file.h 
  Log:
  Replace direct atomic operation for the file refcount witht the
  refcount interface.
  It also introduces the correct usage of memory barriers, as sometimes
  fdrop() and fhold() are used with shared locks, which don't use any
  release barrier.
