Post fix for bug#25122.

into  moonbone.local:/mnt/gentoo64/work/25122-bug-5.0-opt-mysql

When INSERT is done over a view the table being inserted into is 
checked to be unique among all views tables. But if the view contains
self-joined table an error will be thrown even if all tables are used under
different aliases.

The unique_table() function now also checks tables' aliases when needed.

it doesn't select.

This bug was fixed along with bug #16861: User defined variable can 
have a wrong value if a tmp table was used.

There the fix consisted of Item_func_set_user_var overloading the method
Item::save_in_field. Consider the query from the test case:


INSERT INTO foo( bar, baz )
SELECT 
  bar,
  @newBaz := 1 + baz
FROM 
  foo
WHERE 
  quux <= 0.1;

Here the assignment expression '@newBaz := 1 + baz' is represented by an 
Item_func_set_user_var. Its member method save_in_field, which writes the 
value of this assignment into the result field, writes the val_xxx() value, 
which is not updated at this point. In the fix introduced by the patch,
the save_in_field method reads the actual variable value instead.

created for sorting.

Any outer reference in a subquery was represented by an Item_field object.
If the outer select employs a temporary table all such fields should be
replaced with fields from that temporary table in order to point to the 
actual data. This replacement wasn't done and that resulted in a wrong
subquery evaluation and a wrong result of the whole query.

Now any outer field is represented by two objects - Item_field placed in the
outer select and Item_outer_ref in the subquery. Item_field object is
processed as a normal field and the reference to it is saved in the
ref_pointer_array. Thus the Item_outer_ref is always references the correct
field. The original field is substituted for a reference in the
Item_field::fix_outer_field() function.

New function called fix_inner_refs() is added to fix fields referenced from
inner selects and to fix references (Item_ref objects) to these fields.

The new Item_outer_ref class is a descendant of the Item_direct_ref class.
It additionally stores a reference to the original field and designed to
behave more like a field.
