resolve_const_item() assumed to be not called for Item_row items. For
ensuring that DBUG_ASSERT(0) was set there.
This patch adds section for Item_row items. If it can it recursively calls
resolve_const_item() for each item the Item_row contains. If any of the
contained items is null then whole Item_row substitued by Item_null. Otherwise
it just returns.
sql/item.cc:
Fix bug#13356 resolve_const_item() wasn't able to handle Item_row items.
Added section to resolve_const_item() for Item_row items. If it can it
recursively calls resolve_const_item() for each item the Item_row contains. If
any of the contained items is null then Item_row is substituted by Item_null.
Otherwise it just returns.
Comment moved closer to function it belongs to.

The problem was an ab-use of last_rkey_length.
Formerly we saved the packed key length (of the search key)
in this element. But in certain cases it got replaced by
the (packed) result key length.
Now we use a new element of MI_INFO to save the packed key
length of the search key.

thd->allow_sum_func was left 'true' after previous statement thus allowing
sum funcs to be present in conditions.
thd->allow_sum_func should be set to 0 for each query and each prepared
statement reinitialization. This is done in lex_start() and
reset_stmt_for_execute().

Not all args to mysqltest should be added to the MYSQL_TEST environment variable. The MYSQL_TEST var is used when testing mysqltest and --record and result_file should not be set.
The problem was in that the MIN/MAX optimization in opt_sum_query was
replacing MIN/MAX functions with their constant argument without
taking into account that a query has no result rows.

mysql-test/t/func_group.test:

sql/item_sum.cc:
If it is known that a query has no result rows, do not call add()
via the call to Item_sum::no_rows_in_result() which calls reset().
Instead directly call clear() so that the MIN and MAX functions
produce NULL when there are no result rows.
sql/opt_sum.cc:
* Do not apply MIN/MAX optimization when the operand of MIN/MAX is
a constant if it can't be determined whether the query has any
result rows. The reason is that if the query has result rows,
then the result of MIN/MAX is its constant argument, but if the
query result is empty, then the result of MIN/MAX must be NULL
irrespective of its argument.
* The patch also simplifies a bit the branch that hadles COUNT().
