Increase STACK_BUFF_ALLOC to avoid execution_constants test failure on the hpita2.


sql/mysql_priv.h:
  Fix for bug #21476: stack overflow crashes server; error-message stack reservation too small
    - due to the failing execution_constants test on the hpita2, 
      increase STACK_BUFF_ALLOC, that is used in the Item_func::fix_fields() to 
      allocate on the stack a "dummy" buffer large enough for the corresponding exec.

is involved.

The Arg_comparator::compare_datetime() comparator caches its arguments if
they are constants i.e. const_item() returns true. The
Item_func_get_user_var::const_item() returns true or false based on
the current query_id and the query_id where the variable was created.
Thus even if a query can change its value its const_item() still will return
true. All this leads to a wrong comparison result when an object of the
Item_func_get_user_var class is involved.

Now the Arg_comparator::can_compare_as_dates() and the
get_datetime_value() functions never cache result of the GET_USER_VAR()
function (the Item_func_get_user_var class).

  Fixed an allocation routine to detect integer overflow, and as an optimization a check that prevents the number of buffpeks being larger than can possibly fit into memory.

  Changed an index variable from int to uint to the match the type of the variable it's
  being compared with.
      
      Replaced a break statement with a goto statement so that a failure will instead break
  out of the higher level while-loop, instead of just the nested for-loop.
