MDEV-38752 Check that virtual column is a supertype to its expression before substitution

New optimizations were introduced that substitute virtual column
expressions (abbr. vcol expr) with index virtual columns (abbr. vcol
field) in ORDER BY and GROUP BY.

In this patch we introduce checks that the type of a vcol field is the
supertype to its vcol expr, and if not, do not proceed the
optimization. This ensures that the substitution is safe and does not
for example lose information due to truncation.

For simplicity, the version of the check implemented is strict with
100% precision, meaning that there are instances where vcol field is a
supertype to vcol expr, but the check returns false.

Type not covered in tests: Type_handler_null

Thanks to Jarir Khan <[email protected]> for initial patches
addressing this issue.

MDEV-32115: Log checkpoint race with wsrep_sst_method=rsync

Galera snapshot transfer (SST) using the default wsrep_sst_method=rsync
is prone to creating corrupted snapshots. The probability for this is
rather low and might only affect installations that include
ENGINE=InnoDB tables that contain FULLTEXT INDEX.

The function sst_disable_innodb_writes() aims to disable all InnoDB writes
during the time a snapshot transfer (SST) is in progress using the
default wsrep_sst_method=rsync.

The logic based on invoking log_make_checkpoint() almost works, except
for two things: We failed to ensure that fts_optimize_callback() has
stopped executing, and we did not block updates of the log checkpoint
header.

log_checkpoint_low(): Assert that writes to the log are allowed.

buf_flush_page_cleaner(): Do not try to advance the checkpoint while
wsrep_sst_method=rsync is in progress. This prevents the assertion
in log_checkpoint_low() from failing.

fts_optimize_pause(), fts_optimize_resume(): Pause and resume the
fts_optimize_callback().

sst_disable_innodb_writes(): Disable all background writers
before initiating the log checkpoint.

fts_optimize_callback(): Assert that wsrep_sst_method=rsync is not
active, and remove the previous incorrect attempt at fixing this race.

MDEV-37020: Derived table merge optimization does not work for delete and update

A derived table in a multitable DELETE or UPDATE was materialized
while a derived table in an equivalent query using a VIEW was merged.

The cause was a blanket guard in TABLE_LIST::init_derived added by
commit fe89df42686f.  That commit fixed a ROWNUM crash on VIEWs with
ORDER BY, but its derived table guard was wider than it needed to be.

Narrow that guard to the case when the derived table lives inside a
VIEW's body (the case when belong_to_view is set).  A derived table at
the top level of a multitable query will be merged, while a derived
nested table within a VIEW will be materialized.

Narrowing that guard exposes a separate latent bug.  The access check
in multi_update_check_table_access has a branch for VIEWs and another
for 'not VIEWs' which dereferences table->table->map.  A merged
derived table that is not a VIEW fits neither condition.  As is the
case in main.lock_multi_bug38499, when concurrent ALTER on the target
forces the prepared statement to be prepared again, table->table on
the merged derived table might be NULL and this leads to a crash.
Privileges for the underlying base tables are already checked by
multi_update_precheck, so multi_update_check_table_access now returns
early in its else branch when the input is a merged derived table.

MDEV-39213: json range syntax crash

Analysis:
When json is being parsed, the step decreases without a out-of-bound check
resulting in failure.
Fix:
Before decreasing the step, check if it will result into out of bound.

MDEV-35548: Fix out-of-bounds array access in json_get_path_start

json_get_path_start() set p->last_step to p->steps - 1, creating a
pointer before the beginning of the steps[] array. This is undefined
behavior flagged by UBSAN as "index -1 out of bounds for type
json_path_step_t[32]".

Use NULL as the sentinel value instead, and check for NULL in
json_get_path_next() rather than comparing against p->steps.

Backport to 10.6 of commit 4f546897b87144f4219094c5a852d766d5a46b74.

MDEV-39418: Revert most of MDEV-39240 for MDEV-32188

MDEV-39240 fixed how servers before 11.5/11.4-enterprise
accepted timestamps beyond Year 2038 from row-based replication,
which were invalid until 11.5/11.4-enterprise’s MDEV-32188.
MDEV-39240 does not apply after MDEV-32188 extended the valid range,
so those versions should exclude this fix,
as if MDEV-32188 already covers it.

This commit reverts commits 3234045953 and most of f9c34a1442, keeping
only the tweak to the MTR script `include/check_type` for consistency.

MDEV-39494: UBSAN error on division by zero.

An incorrectly backported test from 11.x revealed an UBSAN error in 10.11, so
fix that problem by preventing a division-by-zero from happening.

Remove the other incorrectly backported tests and relabel the retained test
in terms of the current ticket.
