"Stored procedures: crash with function calling itself".

Disallow recursive stored routines until we either make Item's and LEX
reentrant safe or will use spearate sp_head instances (and thus separate
LEX objects and Item trees) for each routine invocation.

(The bug itself was fixed earlier by the patch that fixed bug #5860
 "Multi-table UPDATE does not activate update triggers" and several
 other bugs).

  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.

The reason it happened was that both, JOIN::cleanup() and JOIN::join_free(),
went over all nested joins and called cleanup/join_free for them.
For that:
- split recursive and non-recursive parts of JOIN::cleanup() and
JOIN::join_free()
- rename JOIN::cleanup to JOIN::destroy, as it actually destroys its
  argument
- move the recursive part of JOIN::cleanup to st_select_lex::cleanup
- move the non-recursive part of JOIN::join_free to the introduced
  method JOIN::cleanup().
