For compatibility reasons, add the option to the MariaDB client without
any functional changes besides simply accepting the option and emitting
a warning that it is obsolete.
In MySQL this security related option is compulsory in certain use
cases. When users switch to MariaDB, this client command that used to
work starts failing without a sensible error message. In worst case
users resort to re-installing the mysql client from MySQL.
In MariaDB the option is obsolete and should simply be ignored. Users
however don't have any opportunity to learn that unless the client
program tells them so.
Before:
mysql --enable-cleartext-plugin ...
mysql: unknown option '--enable-cleartext-plugin'
(program terminates)
After:
mysql --enable-cleartext-plugin ...
WARNING: option '--enable-cleartext-plugin' is obsolete.

or slow query log when the log_output=TABLE.
When this happens, we temporary disable by changing log_output until
we've created the general_log and slow_log tables again.
Move </database> in xml mode until after the transaction_registry.
General_log and slow_log tables where moved to be first to be dumped so
that the disabling of the general/slow queries is minimal.
Previously the correct SQL mode for a stored routine or
package was only set before doing the CREATE part, this
worked out for PROCEDUREs and FUNCTIONs, but with ORACLE
mode specific PACKAGEs the DROP also only works in ORACLE
mode.
Moving the setting of the sql_mode a few lines up to happen
right before the DROP statement is writen fixes this.
New Feature:
============
Extend mariadb-binlog command-line tool to allow for filtering
events using GTID domain and server ids. The functionality mimics
that of a replica server’s DO_DOMAIN_IDS, IGNORE_DOMAIN_IDS, and
IGNORE_SERVER_IDS from CHANGE MASTER TO. For completeness, this
patch additionally adds the option --do-server-ids as an alias for
--server-id, which now accepts a list of server ids instead of a
single one.
Example usage:
mariadb-binlog --do-domain-ids=2,3,4 --do-server-ids=1,3
master-bin.000001
Functional Notes:
1. --do-domain-ids cannot be combined with --ignore-domain-ids
2. --do-server-ids cannot be combined with --ignore-server-ids
3. A domain id filter can be combined with a server id filter
4. When any new filter options are combined with the
--gtid-strict-mode option, events from excluded domains/servers are
not validated.
5. Domain/server id filters can be combined with GTID ranges (i.e.
specifications of --start-position and --stop-position). However,
because the --stop-position option implicitly undertakes filtering
to only output events within its range of domains, when combined
with --do-domain-ids or --ignore-domain-ids, output will consist of
the intersection between the filters. Specifically, with
--do-domain-ids and --stop-position, only events with domain ids
present in both argument lists will be output. Conversely, with
--ignore-domain-ids and --stop-position, only events with domain ids
present in the --stop-position and absent from the
--ignore-domain-ids options will be output.

The reason for this fix was that when I tried to run mysql_upgrade
at home to update an old 10.5 installation, mysql_upgrade failed
with warnings about mariadb.sys user not existing.
If the server was started with --skip-grants, there would be no warnings
from mysql_upgrade, but in some cases running mysql_upgrade again could
produce new warnings.
The reason for the warnings was that any access of the mysql.user view
will produce a warning if the mariadb.sys user does not exists.
Fixed with the following changes:
- Disable warnings about mariadb.sys user not existing
- Don't overwrite old mariadb.sys entries in tables_priv and global_priv
- Ensure that tables_priv has an entry for mariadb.sys if the user exists.
This fixes an issue that tables_priv would not be updated if there
was a failure directly after global_priv was updated.
Fix a possible crash on my_free() due to the use of strdup() versus
my_strdup(), and a memory leak.

Problem:
========
When using mariadb-binlog with --raw and --stop-never, events from
the master's currently active log file should be written to their
respective log file specified by --result-file, and shown on-disk.
There is a bug where mariadb-binlog does not flush the result file
to disk when new events are received
Solution:
========
Add a function call to flush mariadb-binlog’s result file after
receiving an event in --raw mode.

This patch also fixes:
MDEV-27690 Crash on `CHARACTER SET csname COLLATE DEFAULT` in column definition
MDEV-27853 Wrong data type on column `COLLATE DEFAULT` and table `COLLATE some_non_default_collation`
MDEV-28067 Multiple conflicting column COLLATE clauses are not rejected
MDEV-28118 Wrong collation of `CAST(.. AS CHAR COLLATE DEFAULT)`
MDEV-28119 Wrong column collation on MODIFY + CONVERT
This commit contains a test for reproducing the issue in MDEV-27649,
where a transaction, executing a prepared statment, is BF aborted.
The scenario, in MDEV-27649 has a transaction which has prepared a PS,
but not yet executed it, and this transaction is then BF aborted in this state.
When the BF aborted transaction tries to execute the PS, it will receive deadlock error.
But, when it tries to execute the PS second time, the node crashes.
Mtr test galera.galera_bf_abort_ps_bind, exercises this scenario.
However, mtr test platform does not have mechanism to control the execution of PS in required detail.
For this purpose, mysqltetst.cc was extended to contain 4 new commands:
PS_prepare - to prepare a prepared statement
PS_bind - to bind values for parameters for the PS
PS_execute - to execute the PS
PS_close - to close the PS
The support for controlling prepared statments in mtr scripts is quite minimal
in this commit. Limitations are:
* only one PS can be used by a connection, at a time
* only input parameters can be bound for the PS
* only varchar, integer or float type of parameters can be bound

Added ability to disable/enable (--disable_view_protocol/--enable_view_protocol) view-protocol in tests.
When the option "--disable_view_protocol" is used util connections are closed.
Added new test for checking view-protocol
Removed all dependencies of command line arguments based on positions in
an array (this kind of code should never have been written).
Instead use option names, which are stable.
