MDEV-25777: JAVA_INCLUDE_PATH and JAVA_INCLUDE_PATH2 not found with out of source configuration and Ninja generator

- As solution `PLUGIN_CONNECT=NO` use early check to disable plugin:
  Solution suggested by wlad@mariadb.com
- `JNI_FOUND` is a internal result variable and should be set with
cached library and header variables (like `JAVA_INCLUDE_PATH`) defined.
  * Note: wrapper cmake/FindJNI.cmake runs first time and cmake native Find<module> returns only cached variable, like `JAVA_INCLUDE_PATH`, results variable are not cached).

Back in 2006 or 2007, when MySQL AB and Innobase Oy existed as
separately controlled entities (Innobase had been acquired by
Oracle Corporation), MySQL 5.1 introduced a storage engine plugin
interface and Oracle made use of it by distributing a separate
InnoDB Plugin, which would contain some more bug fixes and
improvements, compared to the version of InnoDB that was statically
linked with the mysqld server that was distributed by MySQL AB.
The built-in InnoDB would export global symbols, which would clash
with the symbols of the dynamic InnoDB Plugin (which was supposed
to override the built-in one when present).

The solution to this problem was to declare all global symbols with
UNIV_INTERN, so that they would get the GCC function attribute that
specifies hidden visibility.

Later, in MariaDB Server, something based on Percona XtraDB (a fork of
MySQL InnoDB) became the statically linked implementation, and something
closer to MySQL InnoDB was available as a dynamic plugin. Starting with
version 10.2, MariaDB Server includes only one InnoDB implementation,
and hence any reason to have the UNIV_INTERN definition was lost.

- Better, easier to read code (no used of 'random' constants).
- All defines are now unique, so it is easier to find bugs if
  somethings goes wrong.

Other things:
- Created sub function of common code in Aggregator_distinct::setup() and
  Item_func_group_concat::setup() that set item->marker
- More documentation
- Folded a few long lines.
- Allmost all changes in item.cc, sql_lex.cc and sql_window.cc are done

In the code existed just before this patch binding of a table reference to
the specification of the corresponding CTE happens in the function
open_and_process_table(). If the table reference is not the first in the
query the specification is cloned in the same way as the specification of
a view is cloned for any reference of the view. This works fine for
standalone queries, but does not work for stored procedures / functions
for the following reason.
When the first call of a stored procedure/ function SP is processed the
body of SP is parsed. When a query of SP is parsed the info on each
encountered table reference is put into a TABLE_LIST object linked into
a global chain associated with the query. When parsing of the query is
finished the basic info on the table references from this chain except
table references to derived tables and information schema tables is put
in one hash table associated with SP. When parsing of the body of SP is
finished this hash table is used to construct TABLE_LIST objects for all
table references mentioned in SP and link them into the list of such
objects passed to a pre-locking process that calls open_and_process_table()
for each table from the list.
When a TABLE_LIST for a view is encountered the view is opened and its
specification is parsed. For any table reference occurred in
the specification a new TABLE_LIST object is created to be included into
the list for pre-locking. After all objects in the pre-locking have been
looked through the tables mentioned in the list are locked. Note that the
objects referenced CTEs are just skipped here as it is impossible to
resolve these references without any info on the context where they occur.
Now the statements from the body of SP are executed one by one that.
At the very beginning of the execution of a query the tables used in the
query are opened and open_and_process_table() now is called for each table
reference mentioned in the list of TABLE_LIST objects associated with the
query that was built when the query was parsed.
For each table reference first the reference is checked against CTEs
definitions in whose scope it occurred. If such definition is found the
reference is considered resolved and if this is not the first reference
to the found CTE the the specification of the CTE is re-parsed and the
result of the parsing is added to the parsing tree of the query as a
sub-tree. If this sub-tree contains table references to other tables they
are added to the list of TABLE_LIST objects associated with the query in
order the referenced tables to be opened. When the procedure that opens
the tables comes to the TABLE_LIST object created for a non-first
reference to a CTE it discovers that the referenced table instance is not
locked and reports an error.
Thus processing non-first table references to a CTE similar to how
references to view are processed does not work for queries used in stored
procedures / functions. And the main problem is that the current
pre-locking mechanism employed for stored procedures / functions does not
allow to save the context in which a CTE reference occur. It's not trivial
to save the info about the context where a CTE reference occurs while the
resolution of the table reference cannot be done without this context and
consequentially the specification for the table reference cannot be
determined.

This patch solves the above problem by moving resolution of all CTE
references at the parsing stage. More exactly references to CTEs occurred in
a query are resolved right after parsing of the query has finished. After
resolution any CTE reference it is marked as a reference to to derived
table. So it is excluded from the hash table created for pre-locking used
base tables and view when the first call of a stored procedure / function
is processed.
This solution required recursive calls of the parser. The function
THD::sql_parser() has been added specifically for recursive invocations of
the parser.

In NetBSD 9.x and prior, udata is an intptr_t, but in 10.x (current
development branch) it was changed to be a void * for compatibility
with other BSDs a year or so ago.

Unfortunately, this does not simplify the code, as NetBSD 8.x and 9.x
are still supported and will be for a few more years.

and remove usage of RESET MASTER in loops.

- Remove sleep of 0.1 second that was done even when not needed.
- Don't call include/wait_wsrep_ready.inc if NO_WSREP is defined.
- Added NO_WSREP=1 to all atomic tests.
- Use 'select 1' instead of 'show status' to check is server is up.
- Changed RESET MASTER to FLUSH BINARY LOGS to speed up atomic tests.
  To be able to do this, added a new parameter variable to
  show_events.inc to allow one to specify the name of the binary log
  in the output.

Support IF EXISTS in the command that alter index visibility:

  ALTER TABLE ALTER (KEY|INDEX) [IF EXISTS] index_name [NOT] IGNORED

mysql

Fix: Changed error messages, rerecorded results and changed other relevant
files.

- Patch addresses the problem to fix double free of
transaction if it is own transaction.

Other things
- Added lost option '--just-clean'

No crash (probably fixed before). Added test case

The reason was that WSREP code in mysql_create_or_drop_trigge() did
jump to an exit label that did not do proper cleanup of state.
Fixed by ensuring that also WSREP code goes trough the cleanup process.

		FTS add index fails

Problem:
========
InnoDB double frees the table if auxiliary fts table
creation fails and fails to set the dict operation
for the transaction. It leads to failure while
dropping newly added index.

Solution:
=========
  InnoDB should avoid double freeing and set the
dictionary operation of transaction in
fts_create_common_tables()

InnoDB truncate table fails to load the fts stopword table into
cache. In that case, InnoDB double frees the truncate creation
transaction. InnoDB should free the transaction which was
created inside ha_innobase::create.
