1. In case of system-versioned table add row_end into FTS_DOC_ID index
in fts_create_common_tables() and innobase_create_key_defs().
fts_n_uniq() returns 1 or 2 depending on whether the table is
system-versioned.
After this patch recreate of FTS_DOC_ID index is required for
existing system-versioned tables. If you see this message in error
log or server warnings: "InnoDB: Table db/t1 contains 2 indexes
inside InnoDB, which is different from the number of indexes 1
defined in the MariaDB" use this command to fix the table:
ALTER TABLE db.t1 FORCE;
2. Fix duplicate history for secondary unique index like it was done
in MDEV-23644 for clustered index (932ec586aa). In case of
existing history row which conflicts with currently inseted row we
check in row_ins_scan_sec_index_for_duplicate() whether that row
was inserted as part of current transaction. In that case we
indicate with DB_FOREIGN_DUPLICATE_KEY that new history row is not
needed and should be silently skipped.
3. Some parts of MDEV-21138 (7410ff436e) reverted. Skipping of
FTS_DOC_ID index for history rows made problems with purge
system. Now this is fixed differently by p.2.
4. wait_all_purged.inc checks that we didn't affect non-history rows
so they are deleted and purged correctly.
Additional FTS fixes
fts_init_get_doc_id(): exclude history rows from max_doc_id
calculation. fts_init_get_doc_id() callback is used only for crash
recovery.
fts_add_doc_by_id(): set max value for row_end field.
fts_read_stopword(): stopwords table can be system-versioned too. We
now read stopwords only for current data.
row_insert_for_mysql(): exclude history rows from doc_id validation.
row_merge_read_clustered_index(): exclude history_rows from doc_id
processing.
fts_load_user_stopword(): for versioned table retrieve row_end field
and skip history rows. For non-versioned table we retrieve 'value'
field twice (just for uniformity).
FTS tests for System Versioning now include maybe_versioning.inc which
adds 3 combinations:
'vers' for debug build sets sysvers_force and
sysvers_hide. sysvers_force makes every created table
system-versioned, sysvers_hide hides WITH SYSTEM VERSIONING
for SHOW CREATE.
Note: basic.test, stopword.test and versioning.test do not
require debug for 'vers' combination. This is controlled by
$modify_create_table in maybe_versioning.inc and these
tests run WITH SYSTEM VERSIONING explicitly which allows to
test 'vers' combination on non-debug builds.
'vers_trx' like 'vers' sets sysvers_force_trx and sysvers_hide. That
tests FTS with trx_id-based System Versioning.
'orig' works like before: no System Versioning is added, no debug is
required.
Upgrade/downgrade test for System Versioning is done by
innodb_fts.versioning. It has 2 combinations:
'prepare' makes binaries in std_data (requires old server and OLD_BINDIR).
It tests upgrade/downgrade against old server as well.
'upgrade' tests upgrade against binaries in std_data.
Cleanups:
Removed innodb-fts-stopword.test as it duplicates stopword.test
For commands
(1) alter table t1 add partition (partition p2);
(2) alter table t1 add partition (partition px history);
It printed the same error message:
Wrong partitioning type, expected type: `SYSTEM_TIME`
For (1) it is not clear from the syntax that we are trying to add
HASH partition. For (2) it is not clear that the table partitioning is
different than SYSTEM_TIME. Now it prints what type we are trying to
add to what type of partitioning.
Fixed warning unused function rename_field_in_list() for compilation
without partitioning.

don't set vers_write=false if one vers column was used explicitly,
instead do vers_update_fields() for columns that do not have explicit
value. So, if row_start has the value and row_end not, row_end will
get max by default.
* clarify the help text for --system-versioning-insert-history
* move the vers_write=false check from Item_field::fix_fields()
next to other vers field checks in find_field_in_table()
* move row_start validation from handler::write_row() next to
vers_update_fields()
* make secure_timestamp check to happen in one place only,
extract it into a function is_set_timestamp_vorbidden().
* overwriting vers fields is an error, just like setting @@timestamp
* don't run vers_insert_history() for every row
1. system_versioning_insert_history session variable allows
pseudocolumns ROW_START and ROW_END be specified in INSERT,
INSERT..SELECT and LOAD DATA.
2. Cleaned up select_insert::send_data() from setting vers_write as
this parameter is now set on TABLE initialization.
4. Replication of system_versioning_insert_history via option_bits in
OPTIONS_WRITTEN_TO_BIN_LOG.
To prevent ASAN heap-use-after-poison in the MDEV-16549 part of
./mtr --repeat=6 main.derived
the initialization of Name_resolution_context was cleaned up.
