A subquery transformation changes the HAVING clause of the embedding query if the subquery contains
a GROUP BY clause. Yet the split_sum_func2 function was not applied to the modified HAVING clause.
This could result in wrong answers.

and possibly server crash in mysqld v5.0.
Reported MyISAM table was created in mysqld 4.1 and contains varchar field.
When binary files of that table was moved to 5.0, mysqld treats that varchar
field as a string field.
In order to make grouping server calculates group buffer, and because
that field is string server assumes it has fixed length and doesn't add
space for length, but later that field is converted to varchar field.
Due to this, when field values were actually copied, additional space for
length bytes is taken and buffer overrun occurs, which may lead to server crash.
The calc_group_buffer() function now reserves additional space for length
bytes for VAR_STRING fields, like for VARCHAR fields.

When an ambiguous field name is used in a group by clause a warning is issued
in the find_order_in_list function by a call to push_warning_printf.
An expression that was not always valid was passed to this call as the field
name parameter.
mysql-test/r/view.result:
Added a test case for bug #16382.
mysql-test/t/view.test:
Added a test case for bug #16382.
When an ambiguous field name is used in a group by clause a warning is issued
in the find_order_in_list function by a call to push_warning_printf.
An expression that was not always valid was passed to this call as the field
name parameter.
A query with a group by and having clauses could return a wrong
result set if the having condition contained a constant conjunct
evaluated to FALSE.
It happened because the pushdown condition for table with
grouping columns lost its constant conjuncts.
Pushdown conditions are always built by the function make_cond_for_table
that ignores constant conjuncts. This is apparently not correct when
constant false conjuncts are present.

Performed evaluation of constant expressions in having clauses.
If the having condition contains a constant conjunct that is always false
an empty result set is returned after the optimization phase.
In this case the corresponding EXPLAIN command now returns
"Impossible HAVING" in the last column.

The problem has manifested itself in the cases when we have a nested outer join
for which it can be inferred that one of the inner tables is a single row table.

The problem has manifested itself in the cases when we have a nested outer join
for which it can be inferred that one of the inner tables is a single row table.
A table is never considered as a const table if it is used in a nested join
that serves as an inner operand of an outer join.

(Make stored routine variables work according to the standard).
mysql-test/r/type_varchar.result:
Update result file.
mysql-test/t/type_varchar.test:
Add a test for BUG#15588.
sql/field.cc:
- use memmove() instead of memcpy() -- after implementation of WL#2984
(Make stored routine variables work according to the standard) it is
possible to store in the field the value from this field. For instance,
this can happen for the following statement:
SET sp_var = SUBSTR(sp_var, 1, 3);
sql/sp_head.cc:
- Work correctly with String:
- String length has to be be reset before use;
- qs_append() does not allocate memory, so the memory should
be reserved beforehand.

Polishing: should have been done in WL#2984.
