Log message:
Put file descriptors on shared data structures when they are completely
setup, take 3.
LARVAL fd still exist, but they are no longer marked with a flag and no
longer reachable via `fd_ofiles[]' or the global linked list. This allows
us to simplifies a lot code grabbing new references to fds.
All of this is now possible because dup2(2) refuses to clone LARVAL fds.
Note that the `fdplock' could now be release in all open(2)-like syscalls,
just like it is done in accept(2).
