  Fix a regression introduced in rev. 1.107. If an item once had a writer
semantics, and then was reused for next node, it still would be applied
as writer again.
  To fix the regression the decision is made never to alter item->el_flags
after the item has been allocated. This requires checking for overrides
both in ng_dequeue() and in ng_snd_item().

  Details:
  - Caller of the ng_apply_item() knows what is the current access to
    node and specifies it to ng_apply_item(). The latter drops the
    given access after item has beem applied.
  - ng_dequeue() needs to be supplied with int pointer, where it stores
    the obtained access on node.
  - Check for node/hook access overrides in ng_dequeue().
