Title:
  [6.1][7.0][trunk] _product_reserve result is not correct

Status in OpenERP Addons (modules):
  Confirmed

Bug description:
  _product_reserve (stock/stock.py) does not take linked moved into
  account for computation.

  It results in a total mess when using mrp module as a "mrp.production"
  object when confirmed will always create two moves (the first for the
  procurement, and a second one that is in a 'waiting' state and
  attached to the stock.picking list used to check production start
  availability) for each product line:

  "Stock -> Stock" linked to "Stock -> Production" via "move_dest_id" field
   
  The BIG problem is that "_product_reserve" is doing this:

  Counted value INCREASED (++) for : location_id <> stock AND location_dest_id = stock AND state='done'
  Counted value DECREASED (--) for : location_id == stock AND location_dest_id <> stock AND state in ('done', 'assigned')

  As you can see, the first move will never be taken into account, even
  if assigned because "location_id == location_dest_id" and the second
  move is also ignored because it is in a 'waiting' state.

  
  In practice, the final issue is that a product procurement is always valid (if Quantity On Hand > 0.0):
    "from stock: products assigned."
  but the quantity is permanently decreased without exception from procurement.
  So actually, the MRP module cannot be used.
