Current Debian package revision scheme when using
debian/autobake-deb.sh script is:
  '1:VERSION+maria~LSBNAME'

For example if VERSION can be like 10.6.8 and LSBNAME is
buster then version and revision is:
  '1:10.6.8+maria~buster'
Which can lead to problem as distro code names can be lexical unordered.

For example Debian LSBNAME's can be:
  Codename Buster is Debian version 10
  Codename Bookworm is Debian version 11

This happens because in ASCII table
Buster first two digits are 'Bu' and they are in hex 0x42 and 0x75
and Bookworm first digits 'Bo' are they are in hex 0x42 and 0x6F
When apt is upgrading it  means that:
  1:10.6.8+maria~buster is bigger than 1:10.6.8+maria~bookworm
and that leads to problems in dist-upgrade process

To solve problem revision format is changed to:
  '1:VERSION+maria~(deb|ubu)LSBVERSION'

Example for Debian 11 is now:
  1:10.6.8+maria~deb11

and for Ubuntu 22.04 is now:
  1:10.6.8+maria~ubu2204

There are new Variables
 * VERSION which contains whole version string
 * LSBVERSION which contains LSB version of distro
 * LSBID which contains LSB ID (Debian or Ubuntu)
added to debian/autobake-deb.sh.

Also CODENAME is change to LSBNAME as it's more declaritive

MDEV-26127 Assertion `err != DB_DUPLICATE_KEY' failed or InnoDB: Failing assertion: id != 0 on ALTER ... REBUILD PARTITION

During rebuild of partition, the partitioning engine calls
alter_close_table(), which does not unlock and close some table
instances of the target table.
Then, the engine fails to rename partitions because there are table
instances that are still locked.

Closing all the table instance of the target table fixes the bug.

Test prior to this change:

CURRENT_TEST: connect.mysql
mysqltest: At line 485: query 'INSERT IGNORE INTO t3 VALUES (5),(10),(30)' failed: ER_GET_ERRMSG (1296): Got error 122 '(1062) Duplicate entry '10' for key 'PRIMARY' [INSERT INTO `t1` (`a`) VALUES (10)]' from CONNECT

So the ignore table option wasn't getting passed to the remove server.

PageConverter::update_header(): Remove an unnecessary write.
The field that was originally called FIL_PAGE_FILE_FLUSH_LSN only
made sense for the first page of the system tablespace
(initially, for the first page of each file of the system tablespace).
It never had any meaning for .ibd files, and it lost its original
meaning in MariaDB Server 10.8.1 when
commit b07920b6 (MDEV-27199)
removed the ability to start without ib_logfile0.

If the most significant 32 bits of the LSN are nonzero, this
unnecessary write would write the wrong encryption key identifier
to the page. The first page of any file is never encrypted,
so normally those bytes should be 0 for any .ibd file.

The zoneinfo directory is littered with non-timezone information files.

These frequently contain extensions, not present in real timezone files.

Alo leapseconds is frequently there and is not a timezone file.

The else condition is meant to be here to define the functions
if the Red Hat include file isn't there.

(Try 2) (Cherry-pick back into 10.3)

The code that updates semi-join optimization state for a join order prefix
had several bugs. The visible effect was bad optimization for FirstMatch or
LooseScan strategies: they either weren't considered when they should have
been, or considered when they shouldn't have been.

In order to hit the bug, the optimizer needs to consider several different
join prefixes in a certain order. Queries with "obvious" query plans which
prune all join orders except one are not affected.

Internally, the bugs in updates of semi-join state were:
1. restore_prev_sj_state() assumed that
  "we assume remaining_tables doesnt contain @tab"
  which wasn't true.
2. Another bug in this function: it did remove bits from
   join->cur_sj_inner_tables but never added them.
3. greedy_search() adds tables into the join prefix but neglects to update
   the semi-join optimization state. (It does update nested outer join
   state, see this call:
     check_interleaving_with_nj(best_table)
   but there's no matching call to update the semi-join state.
   (This wasn't visible because most of the state is in the POSITION
    structure which is updated. But there is also state in JOIN, too)

The patch:
- Fixes all of the above
- Adds JOIN::dbug_verify_sj_inner_tables() which is used to verify the
  state is correct at every step.
- Renames advance_sj_state() to optimize_semi_joins().
  = Introduces update_sj_state() which ideally should have been called
    "advance_sj_state" but I didn't reuse the name to not create confusion.

DBUG_PUSH_EMPTY is used by thr_mutex.cc.
If there are 4G of DBUG_PUSH_EMPTY calls, then DBUG_POP_EMPTY will
cause a crash when DBUGCloseFile() will try to free an object that
was never allocated.

The assert happens in 10.6 with the following command:

ER_CHECK_NO_SUCH_TABLE was raised because a view does not have
the corresponding TABLE instance connected to TABLE_LIST and the
server interprets the absence as the absence of the table itself.

To fix the problem, we add a check to ensure that the target table
to be swapped with a partition is not a view.

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.

- InnoDB fails to create a fts cache while loading the innodb fts
table which is stored in system tablespace. InnoDB should create
the fts cache while loading FTS_DOC_ID column from system column.

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.

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.

This commit fixes an issue with IST handling in
version 10.9 which is a regression after MDEV-26971
and related to trying to get a non-existent "total"
tag on the IST branch (this tag is only defined in
SST mode).

We cannot permanently change bits in read_partitions in the middle of
processing because ha_rnd_init()/ha_rnd_end() depends on that.

prefer if/skip over require
(works better with debugging, not affected by query log)

This reverts commit 17e0f522.

The counter srv_stats.key_rotation_list_length is never updated, and
therefore Innodb_encryption_key_rotation_list_length will always be 0.

The view INFORMATION_SCHEMA.INNODB_TABLESPACES_ENCRYPTION comes close
to reporting this information.

The counters were added in commit 5e55d1ce
and any code to update them was
inadvertently removed in commit 2e814d47
when applying InnoDB changes from MySQL 5.7.

Let us remove these counters that never reported anything useful. If such
statistics are really needed in a special case, they can be obtained by
instrumenting the code by some means, such as eBPF or a source code patch.

- In best_extension_by_limited_search(), do not check for
  "(remaining_tables & real_table_bit)", it is guaranteed to be true.
  Make it an assert.
- In (!idx || check_interleaving_with_nj())", remove the !idx part.
  This check made sense only in the original version of this function.
- "micro optimization" in check_interleaving_with_nj().
