The GROUP_CONCAT uses its own temporary table. When ROLLUP is present
it creates the second copy of Item_func_group_concat. This copy receives the
same list of arguments that original group_concat does. When the copy is
set up the result_fields of functions from the argument list are reset to the
temporary table of this copy.
As a result of this action data from functions flow directly to the ROLLUP copy
and the original group_concat functions shows wrong result.
Since queries with COUNT(DISTINCT ...) use temporary tables to store
the results the COUNT function they are also affected by this bug.
The idea of the fix is to copy content of the result_field for the function
under GROUP_CONCAT/COUNT from the first temporary table to the second one,
rather than setting result_field to point to the second temporary table.
To achieve this goal force_copy_fields flag is added to Item_func_group_concat
and Item_sum_count_distinct classes. This flag is initialized to 0 and set to 1
into the make_unique() member function of both classes.
To the TMP_TABLE_PARAM structure is modified to include the similar flag as
well.
The create_tmp_table() function passes that flag to create_tmp_field().
When the flag is set the create_tmp_field() function will set result_field
as a source field and will not reset that result field to newly created
field for Item_func_result_field and its descendants. Due to this there
will be created copy func to copy data from old result_field to newly
created field.

It turned out that we also have relied at certain places that

mysql-test/r/trigger.result:

sql/sql_table.cc:
mysql_alter_table():
Removal of strdup() which is no longer necessary allows us to preserve
nice assumption that "(new_db != db || new_table != table_name) indicates
that table will be renamed. So now we really can use this condition to
avoid updating trigger definitions when table is not renamed.
Note that we can't use (alter_info->flags & ALTER_RENAME) condition instead
since it can be also true when we do "ALTER TABLE t1 RENAME TO t1".
