      Bug#27321: Wrong subquery result in a grouping select. · 3113ce63
      evgen@moonbone.local authored
      The Item_outer_ref class based on the Item_direct_ref class was always used
      to represent an outer field. But if the outer select is a grouping one and the 
      outer field isn't under an aggregate function which is aggregated in that
      outer select an Item_ref object should be used to represent such a field.
      If the outer select in which the outer field is resolved isn't grouping then
      the Item_field class should be used to represent such a field.
      This logic also should be used for an outer field resolved through its alias
      name.
      
      Now the Item_field::fix_outer_field() uses Item_outer_field objects to
      represent aliased and non-aliased outer fields for grouping outer selects
      only.
      Now the fix_inner_refs() function chooses which class to use to access outer
      field - the Item_ref or the Item_direct_ref. An object of the chosen class
      substitutes the original field in the Item_outer_ref object.
      The direct_ref and the found_in_select_list fields were added to the
      Item_outer_ref class.
