Use the server's MariaDB::zlib target when built as a submodule

When Connector/C is built inside the MariaDB server tree, pick up the server's
zlib via the MariaDB::zlib target instead of running FIND_PACKAGE(ZLIB), so the
connector uses exactly the same zlib (bundled or system) as the server and no
longer depends on the FindZLIB result-variable signature. Standalone builds are
unchanged - they still fall back to FIND_PACKAGE(ZLIB).

Also stop adding zlib to CMAKE_REQUIRED_LIBRARIES: ZLIB_LIBRARY may now be an
(ALIAS) target which cannot be used inside try_compile() checks, and none of
those checks need zlib.

MDEV-39681 delayed BF aborting with multi master load

Reason for the hanging, and occasional crashes turned out
to be orphaned innodb lock wait request of a BF aborted
local transaction, which had arrived in commit stage.

Reason is that wsrep BF-abort marks a transaction a deadlock
victim out-of-band, so (unlike native deadlock resolution)
the victim can still own a live LOCK_WAIT request;
if that orphaned waiter survives into commit/rollback,
another transaction granting it calls lock_wait_end() cross-thread
and corrupts the victim's state — surfacing as the lock_wait_end,
que_thr_step, and rollback_finish assertions.

This commit has fixes for claering lock wait status of BF aborted
transactions.

Commit has also a new mtr test: galera.galera_bf_abort_orphan_lock
to work as regression test for the fix.

MDEV-39942: use actual_rec_per_key in loose scan sj optimization

While performing loose scan semi-join optimization in
Loose_scan_opt::check_ref_access_part1() [opt_subselect.h],
the filtered value in the explain plan was in-consistent for a table
with index when same data was inserted using "insert into t1 values()...",
and "insert into t1 select * from t2". This is noticed when
rec_per_key[] was used to get the number of records during optimization.

However, when actual_rec_per_key() is used to get the number of records,
we don't notice this discrepancy.

This PR changes the rec_per_key[] usage to actual_rec_per_key() in the
method Loose_scan_opt::check_ref_access_part1() [opt_subselect.h]

MDEV-38147 error 1950 after mariabackup SST with gtid_strict_mode=ON

After a mariabackup SST the joiner could fail with

  ER_GTID_STRICT_OUT_OF_ORDER (error 1950)

while re-binlogging transactions received over IST.

The cause is that the binary log copied from the donor carries a
Gtid_list whose position can be ahead of the storage-engine snapshot:
BACKUP STAGE BLOCK_COMMIT blocks the engine commit (2PC step 3) but not
the binary log write (step 2), so transactions can be present in the
copied binlog that are not committed in the copied engine snapshot.
After the SST the joiner reports the (committed) engine position to the
cluster, IST resends those transactions, and re-binlogging them under
gtid_strict_mode=ON collides with the ahead Gtid_list -> error 1950.
(MDEV-34483 made the engine snapshot stop short of the binlog, which is
what exposed this.)

The copied binary log carries no transactions the joiner needs - only a
Gtid_list - so instead of shipping and then having to truncate/reconcile
it, the joiner now starts a fresh binary log and seeds its GTID position
from the storage-engine checkpoint during recovery. That checkpoint is
the committed cluster position, i.e. exactly where IST resumes, so the
joiner's binary log stays in lockstep with the rest of the cluster and
no out-of-order GTID can occur.

This works for both wsrep_gtid_mode settings; only the binlog domain of
the cluster stream differs:

  - wsrep_gtid_mode=ON : wsrep_gtid_domain_id (cluster writes are
    re-tagged to it), which is the domain stored in the checkpoint;
  - wsrep_gtid_mode=OFF: gtid_domain_id (cluster writes keep the node's
    configured domain).

Async-replica positions (mysql.gtid_slave_pos) are part of the engine
snapshot and survive the SST unchanged, so a Galera node can still serve
as an async master or replica across the SST.

This commit:
- sql/log.cc: adds wsrep_seed_binlog_gtid_state(), called from
  do_binlog_recovery() when the joiner has no binary log, seeding the
  binlog GTID state for the cluster domain to the SE checkpoint position.
- scripts/wsrep_sst_mariabackup.sh: no longer moves the donor's binary
  log into place on the joiner.
- extra/mariabackup: stop flushing and copying the donor's current
  binary log under --galera-info (removed write_current_binlog_file()).
  Its only purpose was to ship that binary log to the joiner, which now
  discards it; flushing needlessly rotated the donor's binary log on
  every SST. xtrabackup_galera_info and xtrabackup_binlog_info are still
  written.
- sql/wsrep_sst.cc: logs the position actually adopted from storage
  (the authoritative post-SST position) rather than the script-reported
  one.
- sql/handler.cc: downgrades the "Discovered discontinuity in recovered
  wsrep transaction XIDs" message in wsrep_order_and_check_continuity()
  from warning to debug level. With parallel appliers a snapshot
  routinely captures prepared XIDs that are not contiguous with the
  engine checkpoint, so this is normal during SST recovery and of no
  value in regular operation; the transactions past the checkpoint are
  re-delivered by the cluster (IST/SST) regardless.
- Adds an MDEV-38147 MTR test reproducing the issue.

MDEV-39776 SHOW CREATE TABLE corrupts `-quoted table options

Two problems:

1. option value specified as `foo bar` was not quoted,
  printed as foo bar, breaking CREATE TABLE.
2. Option value that included */ was printed as is, in unknown
  options when the whole option was commented out, this broke the
  comment: /* opt='val*/ue' */

Fix: simplify value printing, ignore the original quoting,
always print the value quoted as a string. Break comment markers
with an escape (as *\/) if inside a comment.

Note, cannot use `-quoting, because \-escapes don't work inside,
backticks, so */ cannot be broken.

MDEV-37781 ASAN build crashes on deep query with low thread stack

check_stack_overrun() was compiled out under ASAN, so a deeply nested

ER_STACK_OVERRUN_NEED_MORE.

Since MDEV-34533 (Monty) the stack usage seems to be accounted correctly

too.

MDEV-38243 Write binlog row events for changes done by cascading FK operations

This commit implements a feature which changes the handling of cascading foreign
key operations to write the changes of cascading operations into binlog.
The applying of such transaction, in the slave node, will apply just the binlog
events, and does not execute the actual foreign key cascade operation.
This will simplify the slave side replication applying and make it more predictable
in terms of potential interference with other parallel applying happning
in the node.

This feature can be turned ON/OFF by new variable:
rpl_use_binlog_events_for_fk_cascade, with default value OFF

The actual implementation is largely by windsurf.

The commit has also mtr tests for testing rpl_use_binlog_events_for_fk_cascade
feature:  rpl.rpl_fk_cascade_binlog_row, rpl.rpl_fk_set_null_binlog_row and

MDEV-40176: field_charset()->charpos(blob..) called with NULL

Problem:
  When `my_charpos_mb()` is called by `Field_blob::get_key_image_itRAW`
  with a start/end both being NULL. Because of this the blob_length
  must have been 0.

Fix:
  Rather than relying on character set functions to calculate the
  storage of nothing, bypass the calculation as the charpos() isn't
  going to return a value less than 0 (the blob_length).

MDEV-40179 Found N prepared transactions after mariabackup SST

With log_bin=ON a transaction is committed via two-phase commit (the
binary log is the second participant), so it passes through the InnoDB
XA-prepare state. While a donor is held in BLOCK_COMMIT for a mariabackup
backup, its parallel appliers (wsrep_slave_threads > 1) leave one or more
such writesets prepared-but-not-yet-committed, and the snapshot captures
them. On a freshly SST'd joiner nothing resolves these prepared
transactions: binlog crash recovery does not run (the joiner has no in-use
binlog to recover from), and the wsrep continuity-based commit is inactive
because wsrep_emulate_bin_log is FALSE when log_bin is ON. The leftover
prepared transactions then abort startup with "Found <N> prepared
transactions!". Note this does not depend on the prepared set being
non-contiguous - even a contiguous run aborts, because nothing commits
or rolls it back.

Rollback these transactions in xarecover_handlerton().

Use the server's MariaDB::zlib target when built as a submodule

When Connector/C is built inside the MariaDB server tree, pick up the server's
zlib via the MariaDB::zlib target instead of running FIND_PACKAGE(ZLIB), so the
connector uses exactly the same zlib (bundled or system) as the server and no
longer depends on the FindZLIB result-variable signature. Standalone builds are
unchanged - they still fall back to FIND_PACKAGE(ZLIB).

Also stop adding zlib to CMAKE_REQUIRED_LIBRARIES: ZLIB_LIBRARY may now be an
(ALIAS) target which cannot be used inside try_compile() checks, and none of
those checks need zlib.
