MDEV-39813 ST_GeomFromGeoJSON does not control recursion depth

Geometry::create_from_json reset the killedptr and the stack
depth (stack_p) every time json_scan_start was called. We save/
restore these values so that the ST_GeomFrom_GeoJSON can be killed
and incur timeout, and also so that its depth measurement is kept.

Test case an bug report thanks to byteoverride.

wsrep_causal_reads was deprecated in 10.1.3 and removed in 11.3.1.
Put in place the equivalent (and default) wsrep_sync_wait=0.

Amend a few early comments to show MariaDB as our product.

Add libFuzzer target for MariaDB replication event parsing

Introduces `rpl_fuzzer`, a LLVMFuzzerTestOneInput harness designed to
actively fuzz the replication stream parser (`mariadb_rpl_fetch`) and
row extraction mechanisms (`mariadb_rpl_extract_rows`).

Key design choices implemented in the harness:
- Bypasses traditional file I/O overhead by using `/dev/shm` virtual
  RAM disk files to safely leverage high-concurrency multi-core execution.
- Includes a dynamic stream-alignment scanner that searches for the
  `\xFEbin` magic signature, stripping raw network wrappers from seed inputs.
- Implements synchronized cross-event state tracking (pinning the last
  seen TABLE_MAP_EVENT) to properly feed and exercise the deep
  `mariadb_rpl_extract_rows` column-unpacking logic.

This harness effectively hardens the library against multi-byte integer
underflows, stack buffer smashing, and invalid metadata cross-references.

MDEV-39541 mem_pressure::~mem_pressure() causes a crash on bootstrap

Fill in the anomaly shutdown paths of InnoDB to include call to
buf_mem_pressure_shutdown now that MDEV-39585 provides some
proper calls shutdown InnoDB and other plugins during the shutdown
under --bootstrap.

Alternate: destructor attribute on buf_mem_pressure_shutdown would
acheive the same thing and given Linux compilers are capabile of
this. This is possible as mem_pressure is currently implemented
in Linux only.

MDEV-40048 [to-squash] Allow trigger and LOCK TABLES to work with range interval auto partitioning

When a range interval auto partitioned table is the target of a
trigger, the triggering statement is not necessarily one that would
cause the auto-creation of new partitions, so we need to account for
that.

Also added support for LOCK TABLES ... WRITE.

Improved tests coverage by adapting tests from versioning.partition.

MDEV-39451 Accounting for truncation to value_max_length in the ntile comparison

When truncation to value_max_length in ntile function happens, the
cached string value is the truncated string. For the purpose of
comparison to determine the size of the current partition, it should
not compare the original string with the truncated string.

MDEV-39585: Support SHUTDOWN command on Windows in bootstrap

Don't perform mysqld_win_initiate_shutdown under --bootstrap when
triggered by SHUTDOWN. With this we don't perform any service
interactions.

Then the shutdown can proceeded without then hard process termination
in mysqld_win_initiate_shutdown. This previously occurred because the
handle_connections_win() was never called in --bootstrap and therefore
startup_complete() was false.

Thanks Vladislav Vaintroub for investigation and providing
implementation guidance.

MDEV-39384 Use index in TR_table::query

TR_table::query() used table scan. Now utilize the index if possible,
with minimum validity detection. Getting trx_id by commit_ts is still
suboptimal is it does two index accesses (as limited by fields in
commit_ts index).

When the index detection fails TR_table::query() falls back to
original table scanning method.

MDEV-39450: Memory corruption: overlapping memory ranges in `Field_longstr::compress` on UPDATE of compressed column

Problem:
  Values shorter than `column_compression_threshold` (default 100) are
  stored uncompressed. Reading such a column returns a pointer into that
  buffer rather than a copy.

  When the new value is a substring of the column that aliases this
  buffer at a non-zero offset, e.g. `RIGHT(c,n)` or `SUBSTRING(c,n)`,
  the source and destination overlap, and the `memcpy()` in the "store
  uncompressed" path copies overlapping regions, which is undefined
  behaviour.

Fix:
  Replace `memcpy` with `memmove` to avoid copying between overlapping
  memory regions.

MDEV-39585 mariadb bootstrap fails to perform plugin deinitalization

mariadbd under --bootstrap failed to preform plugin deinitialization.

The sleep(2);exit is removed and replaced to a goto termination label
to perform the same shutdown procedure of the server after all the
connection closing.

To prevent a compile error about char *user being uninitialized
this sql_print_information(ER_DEFAULT(ER_NORMAL_SHUTDOWN)) is moved to
its own block. The memory free did need to occur in the bootstrap mode
too to avoid memory leak errors.

wait_for_signal_thread_to_end(), was previously in close_connections()
however its required too for --bootstrap.

MDEV-39829/MDEV-33532 s3.debug test failure

MDEV-39516 corrected the interface with curl particularly around
passing options.

After this the s3.debug actually enabled curl debugging like is
was meant to. With this enabled, there are addition s3_test_ pattens
in the result file, from the error log where curl correctly provide
debug message.

ps-protocol test also failed under MDEV-33532 where a differnet
number of entries was recored.

Correct variations by using the $database/$table rather than just the
s3_test_ pattern.

As the purpose of this test is to check if s3_debug is dynamic, the
second part of the test searches for a previously, under s3_debug=1,
table t2 interaction, where the results should be NOT_FOUND.

Remove count from the result file to allow for different curl versions
and the possibiliy of being run under ps-protocol.

MDEV-37615: Clang based static analysis false postive reports on UNINIT_VAR

Clang upstream bug https://github.com/llvm/llvm-project/issues/173210
shows that a "int x=x" construct will in the intermediate representation
have code to read from x. With this generated sanitizer=undefined and
static analyzers will all see the uninitialized read and write.

Because clang has a stronger implementation of following paths to
uninitialized variables, "#define UNINIT_VAR(x) x" is the which
is what our release binaries use is the ideal path for this compiler.

Clang based compilers with error during compilation if any
uninitialized behaviour is detected at compile time because of
0c80ddb519bd06efbd7ccf2a2487b2503cd16db5.

MDEV-32726: Fix failing test for freebsd for json

(10.6 backport)

Json test about max statement time fails with freebsd because on some
architectures the test might execute faster and the statement may not fail.

To simulate failure regardless of architecture, introduce a wait of seconds
longer than the max_statement_time.

MDEV-28404 JSON functions don't respect KILL QUERY

Or max_statement_time limit or MAX_DEPTH.

Correct interuptability and depth checking of:
* JSON_CONTAINS
* JSON_CONTAINS_PATH
* JSON_EXISTS
* JSON_EXTRACT
* JSON_KEYS
* ST_GeomFromGeoJSON

Populate in the json library the killed as a specific
error message. As the json library has a killed_ptr
is approprate it handles it.

As json_report_error now processes the killed there's
no need of thd->check_killed().

Verified that the path after every json_scan_next, the
location of checking the killed_ptr, reports errors
correctly.

MDEV-30518: JSON functions cannot be killed on big-endian (backport)

Backport to 10.6 without JSON_OVERLAPS

The json_engine killed_ptr was of type uchar however the enum
in the server is dependant on the architecture. On big-endian
architectures like IBM Z, retreiving a uchar* retreived the
unmodifed part of the THD->kill enum location and was always 0.

As C++11 allows enums to inherit a type, used uint32_t as the base
class of killed_state type in the server and used uint32_t in the
json library.

reload_acl_and_cache required an expression change to avoid
the compile error:
sql/sql_reload.cc:472:24: error: enumerated and non-enumerated
type in conditional expression [-Werror=enum-conversion]
  472 |  return result || (thd ? thd->killed : 0);

Added the kill_ptr assignment the following functions can be
killed:
* Item_func_json_depth::val_int
* Item_func_json_type::val_str
* Item_func_json_length::val_int

Item_func_json_array_append::val_str, check_killed() only applied
to json_error: label and not return_null.

Item_func_json_format::val_str(), corresponding to the SQL,
json_compact, json_detailed, json_loose - add debug instrumentation
for the func_json_notembedded test.

MDEV-26726 (fcd345de485f) added a json_pause_execution sync point
however the test case used debug_max_statement_time, which doesn't
exist. Fix the sync point name in the test.
