- Put back the assert on SQL layer at the right location
- Adjust rdb_pack_with_make_sort_key to work around the assert (like
it is done at other palaces): MyRocks may need to pack a column
value even when the column is not in the read set.
... due to different index statistics
Make statistics calculations in MariaRocks produce the same values
that MyRocks produces.
Added a comment in rdb_datadic.cc
In MariaDB, Field::make_sort_key stores NULL-indicator byte for
the field.
In MySQL, it doesn't, so MyRocks stores the NULL-indicator itself.
Switch to using Field::sort_string, which is the same as
Field::make_sort_key in MySQL.
