Improve and add more languages for the ERROR 1476: Foreign Server
already exists.

The debian/mariabd-plugin-columnstore.install should
not have been committed. It was removed on other branches,
just 10.6 was missed. This prevented packages being built
because the debain/control wasn't populated.

Commit introduces automatic detection which supported
Perl MariaDB DBI driver is available:

 * DBD::mysql
 * DBD::MariaDB

If nothing is then bail out and die

Current Detection prefers Perl DBD:MariaDB driver.

This is mainly for older Linux distros or Windows which does not
have Perl DBD:MariaDB packaged or does not want to use Perl cpan command.

Improve and add more languages for the ERROR 1476: Foreign Server
already exists.

When reading the man page of e.g. 'mysql' on a system with MariaDB
installed one would actually see the man page of 'mariadb'. However the
man page had no indication of the page being for 'mariadb', which was
confusing for users.

Fix this by updating the man page title lines to use mariadb-* instead
of mysql* for MariaDB binaries that are drop-in replacements for MySQL
equivalents, indicating that the commands are actually of the MariaDB
version.

In long term, all the commands in man pages should be replaced by their
MariaDB counterparts. Update the title lines as a start, and only those
that exist as symlinks to their MariaDB counterparts.

Before:

    man mariadb-upgrade | head -n 1
    MYSQL_UPGRADE(1) ...

After:

    man mariadb-upgrade | head -n 1
    MARIADB-UPGRADE(1) ...

Depending on OpenSSL version, and at least in 3.0.3, the client-side socket
timeout is reported as generic error (SSL_ERROR_SYSCALL), losing further
details (both errno and GetLastError() return 0). This results in client
reporting "Unknown OpenSSL error" 2026, instead of another generic
"Lost connection to server during query" 2013

Adjusted test case.

OpenSSL 3.0.0+ does not support EVP_MD_CTX_FLAG_NON_FIPS_ALLOW any longer.
In OpenSSL 1.1.1 the non FIPS allowed flag is context specific, while
in 3.0.0+ it is a different EVP_MD provider.

Fixes #2010

This reverts commit c9beef43, because
we have OpenSSL 3.0 support here.

Summary of changes

- MD_CTX_SIZE is increased

- EVP_CIPHER_CTX_buf_noconst(ctx) does not work anymore, points
  to nobody knows where. The assumption made previously was that
  (since the function does not seem to be documented)
  was that it points to the last partial source block.
  Add own partial block buffer for NOPAD encryption instead

- SECLEVEL in CipherString in openssl.cnf
  had been downgraded to 0, from 1, to make TLSv1.0 and TLSv1.1 possible
   (according to https://github.com/openssl/openssl/blob/openssl-3.0.0/NEWS.md
   even though the manual for SSL_CTX_get_security_level claims that it
   should not be necessary)

- Workaround Ssl_cipher_list issue, it now returns TLSv1.3 ciphers,
  in addition to what was set in --ssl-cipher

- ctx_buf buffer now must be aligned to 16 bytes with openssl(
  previously with WolfSSL only), ot crashes will happen

- updated aes-t , to be better debuggable
  using function, rather than a huge multiline macro
  added test that does "nopad" encryption piece-wise, to test
  replacement of EVP_CIPHER_CTX_buf_noconst

The variable, spider_buffer_size, is used nowhere in the MariaDB Community Server.

Package mariadb-test-data has test files
in directory '/usr/share/mysql/mysql-test/' which are not UTF-8
encoded and they should not be as they are for testing.

package also have Lintian warnings for files that
are not in correct place in directory 'usr/share/mysql/mysql-test'
but as they are all are test results they are not in incorrect place

At last there is intentional use for some repeated directories so
they are false-positives and should be suspended

Cause: a copy of the joined TABLE_LIST is created during multi_update::prepare
and TABLE::pos_in_table_list of the tables are set to point to the new
TABLE_LIST object. This prevents some optimization steps to perform correctly.
Solution: do not update pos_in_table_list during multi_update::prepare

MDEV-14642 Assertion 'table->s->db_create_options == part_table->s->db_create_options' failed in compare_table_with_partition

When trying to execute ALTER TABLE EXCHANGE PARTITION with different
definitions, assertion

    table->s->db_create_options == part_table->s->db_create_options

failed in compare_table_with_partition().

However, this execution should not be allowed since executing
'exchange partition' requires the identical structure of the two tables.

To fix the problem, I deleted the assertion code and added code that
returns an error that indicates tables have different definitions.

that is not in binlog.

Post-crash recovery of --rpl-semi-sync-slave-enabled server
failed to recognize a transaction in-doubt that needed rolled back.
A prepared-but-not-in-binlog transaction gets committed instead
to possibly create inconsistency with a master (e.g the way it was observed
in the bug report).

The semisync recovery is corrected now with initializing binlog coordinates
of any transaction in-doubt to the maximum offset which is
unreachable.
In effect when a prepared transaction that is not found in binlog
it will be decided to rollback because it's guaranteed to reside
in a truncated tail area of binlog.

Mtr tests are reinforced to cover the described scenario.

commit 84984b79 is null-merged

This commit sends a flag indicating the presence of the "--bypass"
option from the donor node to the joiner nodes during rsync IST,
because without such a flag it is impossible to distinguish IST
from the SST on the joiner nodes (in IST/SST scripts, because the
"--bypass" option is still not passed to scripts from server code).
Specifically, this fixes an issue with binary logs disappearing
after IST (via rsync). There are also changes to diagnostic messages
here that will make it easier to diagnose script-related problems
in the future when debugging and when checking the logs. This commit
also adds more robust signal handlers - to handle exceptions during
script execution. These handlers won't mask some crashes and it
also unifies exit codes between different scripts. These changes
have already been helpful to debugging "bypass" flag handling.
