Fixed the results of a test for group_concat.
  After the fix foor bug #11639 the results became
  correct.
olap.result, olap.test:
  Added a test case for bug #11639.
sql_select.cc:
  Fixed bug #11639: a wrong result set when using a view
  instead of the underlying table in a rollup query 
  executed through filesort.
  The old code did not take into account that we always
  use an Item_ref object when referring to a view column.
item.h:
  Fixed bug #11639.
  Now if two Item_ref items ref1 and ref2 refer to the same field
  then ref1->eq(ref2) returns 1.

Make sure to cleanup the items for a cursor query after each open, otherwise
it's done too late, after the run-time mem_root is freed.

open cursor after mysql_stmt_execute" + post-review fixes.
The bug was caused by wrong flags in stmt->server_status on the client
side: if there was no cursor, the server didn't send server_status
flags to the client, and the old flags were used to set up the
fetch function of a statement. Consequently, stmt_read_row_from_cursor was
used when there was no cursor. The fix fixes the server to always
send server flags to the client.

  Fixed a compilation error.

CURSOR_TYPE_READ_ONLY select within select".
The bug was caused by the reset of thd->mem_root to thd->main_mem_root in 
Item_subselect::exec, which in turn triggered too early free_root() for
data which was needed on subsequent fetches from a cursor.
This reset also caused a memory leak in stored procedures, as 
subsequent executions of instructions containing a subselect
were allocating memory in thd->main_mem_root, which is not freed
until the end of the entire SP, instead of the per-call mem_root,
which is freed in the end of execution of the instruction.

  Added a test case for bug #10031.
opt_range.cc:
  Fixed bug #10031: range condition was not used with
  views. Range analyzer did not take into account that
  view columns were always referred through Item_ref.
