MDEV-27037 added functionality to warn users that a specified
stop-position or stop-datetime was never reached. It only worked for
local files though. The patch in MDEV-35528 changed the
implementation for stop-datetime to work to provide the warning also
when using --read-from-remote-server. The PR for that MDEV (#3670)
was limited to only the stop-datetime field.
This patch updates the --stop-position warning to also work with
--read-from-remote-server.

Good news:
GCC now checks your `my_snprintf` (direct) calls (`-Wformat` was on);
Bad news:
The build process no longer lets your incorrect
formats/arguments sneak past (`-Werror` was also on).
As such, this commit also migrates all direct `my_snprintf` calls from
the old specifiers to MDEV-21978’s new `-Wformat`-compatible suffixes.
The next commits will cover non-direct calls to `my_snprintf`.
(I call them “`my_snprintf` descendants”.)
This commit does not update the ABI records because
there’re more ABI “changes” to come – half a dozen
`include/mysql/plugin_*.h.pp`s are now missing the new `__attribute__`s.
* rpl.rpl_system_versioning_partitions updated for MDEV-32188

In Log_event::read_log_event(), don't use IO_CACHE::error of the relay log's
IO_CACHE to signal an error back to the caller. When reading the active
relay log, this flag is also being used by the IO thread, and setting it can
randomly cause the IO thread to wrongly detect IO error on writing and
permanently disable the relay log.
This was seen sporadically in test case rpl.rpl_from_mysql80. The read
error set by the SQL thread in the IO_CACHE would be interpreted as a
write error by the IO thread, which would cause it to throw a fatal
error and close the relay log. And this would later cause CHANGE
MASTER to try to purge a closed relay log, resulting in nullptr crash.
SQL thread is not able to parse an event read from the relay log. This
can happen like here when replicating unknown events from a MySQL master,
potentially also for other reasons.
Also fix a mistake in my_b_flush_io_cache() introduced back in 2001
(fa09f2cd7e) where my_b_flush_io_cache() could wrongly return an error set
in IO_CACHE::error, even if the flush operation itself succeeded.
Also fix another sporadic failure in rpl.rpl_from_mysql80 where the outout
of MASTER_POS_WAIT() depended on timing of SQL and IO thread.

Fix regression introduced by commits 9588526 which attempted to address
MDEV-27037. With the regression, mariadb-binlog cannot process multiple
log files when --stop-datetime is specified.
The change is to keep recording timestamp of last processed event, and
after all log files are processed, if the last recorded timestamp has not
reached specified --stop-datetime, it will emit a warning. This applies
when processing local log files, or log files from remote servers.

Do not use the magic value 0xffffffff as meaning "no --stop-datetime option
specified", as this is a valid timestamp value. Use an explicit boolean flag
instead.

Only `mysql` client program was using $MYSQL_HOST as the default host.
Add the same feature in most other client programs but using
$MARIADB_HOST instead.

There are two problems.
First, replication fails when XA transactions are used where the
slave has replicate_do_db set and the client has touched a different
database when running DML such as inserts. This is because XA
commands are not treated as keywords, and are thereby not exempt
from the replication filter. The effect of this is that during an XA
transaction, if its logged “use db” from the master is filtered out
by the replication filter, then XA END will be ignored, yet its
corresponding XA PREPARE will be executed in an invalid state,
thereby breaking replication.
Second, if the slave replicates an XA transaction which results in
an empty transaction, the XA START through XA PREPARE first phase of
the transaction won’t be binlogged, yet the XA COMMIT will be
binlogged. This will break replication in chain configurations.
The first problem is fixed by treating XA commands in
Query_log_event as keywords, thus allowing them to bypass the
replication filter. Note that Query_log_event::is_trans_keyword() is
changed to accept a new parameter to define its mode, to either
check for XA commands or regular transaction commands, but not both.
In addition, mysqlbinlog is adapted to use this mode so its
--database filter does not remove XA commands from its output.
The second problem fixed by overwriting the XA state in the XID
cache to be XA_ROLLBACK_ONLY, so at commit time, the server knows to
rollback the transaction and skip its binlogging. If the xid cache
is cleared before an XA transaction receives its completion command
(e.g. on server shutdown), then before reporting ER_XAER_NOTA when
the completion command is executed, the filter is first checked if
the database is ignored, and if so, the error is ignored.

Previously, when running mysqlbinlog without providing a binlog file, it
would print the entire help text, which was very verbose and made it
difficult to identify the actual issue.
Now change the behavior to print a more concise error message instead:
"ERROR: Please provide the log file(s). Run with '--help' for usage instructions."
This makes the error output more user-friendly and easier to understand,
especially when running the tool in scripts or automated processes.

insecure passwordless logins are common in test environment, let's
not break them. practically, it hardly makes sense to have strong
MitM protection if an attacker can simply login without a password.
