Fixed bug #11088: a crash for queries with GROUP BY a BLOB column + COUNT(DISTINCT...) due to an attempt to allocate a too large buffer for the BLOB field. Now the size of the buffer is limited by max_sort_length. group_by.test, group_by.result: Added a test case for bug #11088.

In Item_ref::Item_ref set maybe_null (and other fields fix_fields sets) to be the same as in (*ref), because Item_ref::fix_fields() will not be called. Previously maybe_null was 0 always and this produced a bogus state where maybe_null==0 && is_null() == true which broke evaluation for some upper-level Items, like AND and OR.

is a GROUP BY a column that is not NOT NULL and ORDER BY is done by another column. Even better fix would be to make a separate function for this.
