Dump sequences first.
This atch made to keep it small and
to keep number of queries to the server the same.
Order of tables in a dump can not be changed
(except sequences first) because mysql_list_tables
uses SHOW TABLES and I used SHOW FULL TABLES.
- Original patch was contributed by Jani Tolonen <jani.k.tolonen@gmail.com>
https://github.com/an3l/server/commits/bb-10.3-anel-MDEV-21786-dump-sequence
which distinguishes data structure (linked list) of sequences from
tables.
- Added standard sql output to prevent future changes
of sequences and disabled locks for sequences.
- Added test case for `MDEV-20070: mysqldump won't work correct on
sequences` where table column depends on sequence value.
- Restore sequence last value in the following way:
- Find `next_not_cached_value` and use it to `setval()`
- We just need for logical restore, so don't execute `setval()`
- `setval()` should be showed also in case of `--no-data` option.

- Changed names of SEQUENCE table columns to be more close to ANSI
- Fixed error message for SHOW SEQUENCE non_existing_sequence
- Allow syntax CACHE +1
- Fixed ALTER TABLE for TEMPORARY sequences.
- Test with LOCK TABLES
- Test mysqldump
- Don't update rows for sequence tables if values doesn't change. This is
needed as InnoDB gives an error for updates where values doesn't change.
