          Dont expose em->shared to the outside world before its properly
          initialized. Might not affect anything but its at least a better
          coding style.
  
          Dont expose em via p->p_emuldata until its properly initialized.
          This also enables us to get rid of some locking and simplify the
          code because we are workin on a local copy.
  
          In linux_fork and linux_vfork create the process in stopped state
          to be sure that the new process runs with fully initialized emuldata
          structure [1]. Also fix the vfork (both in linux_clone and linux_vfork)
          race that could result in never woken up process [2].
