MDEV-10139 Support for SEQUENCE objects
- SETVAL(sequence_name, next_value, is_used, round) - ALTER SEQUENCE, including RESTART WITH Other things: - Added handler::extra() option HA_EXTRA_PREPARE_FOR_ALTER_TABLE to signal ha_sequence() that it should allow write_row statments. - ALTER ONLINE TABLE now works with SEQUENCE:s
