The IN() function uses agg_cmp_type() to aggregate all types of its arguments
to find out some common type for comparisons. In this particular case the 
char() and the int was aggregated to double because char() can contain values
like '1.5'. But all strings which do not start from a digit are converted to
0. thus 'a' and 'z' become equal. 
This behaviour is reasonable when all function arguments are constants. But 
when there is a field or an expression this can lead to false comparisons. In
this case it makes more sense to coerce constants to the type of the field
argument.

The agg_cmp_type() function now aggregates types of constant and non-constant
items separately. If some non-constant items will be found then their
aggregated type will be returned. Thus after the aggregation constants will be
coerced to the aggregated type.

  Added test case for bug#18360: Incorrect type coercion in IN() results in false comparison.

  aggregated type will be returned. Thus after the aggregation constants will

In multi-table delete a table for delete can't be used for selecting in
subselects. Appropriate error was raised but wasn't checked which leads to a
crash at the execution phase.

The mysql_execute_command() now checks for errors before executing select
for multi-delete.


mysql-test/t/multi_update.test:
  Added test case for bug#19225: unchecked error results in server crash

sql/sql_parse.cc:
  Fixed bug#19225: unchecked error results in server crash
  The mysql_execute_command() now checks for errors before executing select for multi-delete.

The Item_func_concat::val_str() function tries to make as less re-allocations
as possible. This results in appending strings returned by 2nd and next
arguments to the string returned by 1st argument if the buffer for the first
argument has enough free space. A constant subselect is evaluated only once 
and its result is stored in an Item_cache_str. In the case when the first
argument of the concat() function is such a subselect Item_cache_str returns
the stored value and Item_func_concat::val_str() append values of other
arguments to it. But for the next row the value in the Item_cache_str isn't
restored because the subselect is a constant one and it isn't evaluated second
time. This results in appending string values of 2nd and next arguments to the 
result of the previous Item_func_concat::val_str() call.

The Item_func_concat::val_str() function now checks whether the first argument 
is a constant one and if so it doesn't append values of 2nd and next arguments
to the string value returned by it.


mysql-test/t/func_concat.test:
  Added test case for bug#16716: subselect in concat() may lead to a wrong result.
