Working on MDEV-11832: Srcdef performance enhancement
This require to mark place holders into srcdef to indicate where to insert
the where/having clauses that are retrieved in push_cond.
However this also make necessary to handle aliases in the srcdef.
This was the opportunity to base all external tables on common classes
called EXTDEF, TABEXT and EXTCOL.

- in DOMNODELIST::DropItem

- Crash in discovery with libxml2 in XMLColumns because:
            if (!tdp->Usedom)    // nl was destroyed

is executed with vp->pn uninitialized. Fixed by adding:
          vp->pn = node;
line 264.
-In discovery with libxml2 some columns are not found.
Because list was not recovered properly, nodes being modified and not reallocated.
Fixed lines 214 and 277.

Make some global fil_crypt_ variables static.

fil_close(): Call mutex_free(&fil_system->mutex) also in InnoDB, not
only in XtraDB. In InnoDB, sync_close() was called before fil_close().

innobase_shutdown_for_mysql(): Call fil_close() before sync_close(),
similar to XtraDB shutdown.

fil_space_crypt_cleanup(): Call mutex_free() to pair with
fil_space_crypt_init().

fil_crypt_threads_cleanup(): Call mutex_free() to pair with
fil_crypt_threads_init().

Try to stabilize test cases. These test behave badly when run in certain order.

The reason was that the test was reusing the same log file without deleting it between tests.
Fixed by creating a new log file as part of the test

  Problem:- While running individual tests of Galera_3nodes ,
  We get warnings like '[Warning] WSREP: Could not open state file
  for reading: '. And because of this individual tests fails.

  Solution:- We change suite.pm of Galera_3nodes to supress these warnings.

Essentially revert MDEV-6759, which addressed a double free of memory
by removing the freeing altogether, introducing the memory leaks.
No double free was observed when running the test suite -DWITH_ASAN.

Replace some mem_heap_free(foreign->heap) with dict_foreign_free(foreign)
so that the calls can be located and instrumented more easily when needed.

mysql_release.cmake set WITH_JEMALLOC=static, which makes windows
builds fail since there is no jemalloc either static or shared there

Updated sysvars_wsrep.result file.

In file sql/opt_range.cc,when calculate_cond_selectivity_for_table() is called with optimizer_use_condition_selectivity=4 then
	- thd->no_errors is set to 1
	- the original value of thd->no_error is not restored to its original value
	- this is causing the assertion to fail in the subsequent queries

Fixed by restoring the original value of thd->no_errors

     Tasks:-
         Changes in wsrep_dirty_reads variable
         1.) Global + Session scope (Current: session-only)
         2.) Can be set using command line.
         3.) Allow all commands that do not change data (besides SELECT)
         4.) Allow prepared Statements that do not change data
         5.) Works with wsrep_sync_wait enabled

This reverts commit 7ed5563b.

Reduce the number of calls to encryption_get_key_get_latest_version
when doing key rotation with two different methods:

(1) We need to fetch key information when tablespace not yet
have a encryption information, invalid keys are handled now
differently (see below). There was extra call to detect
if key_id is not found on key rotation.

(2) If key_id is not found from encryption plugin, do not
try fetching new key_version for it as it will fail anyway.
We store return value from encryption_get_key_get_latest_version
call and if it returns ENCRYPTION_KEY_VERSION_INVALID there
is no need to call it again.

After applying/replaying the transaction, the memory that
stored the query string was also wrongly freed.

... causes MariaDB to crash

On error, the wsrep replication buffer (binlog) is dumped to a file
to aid investigations. In order to also include the binlog header,
FDLE object is also needed. This object is only available for wsrep-
threads.
Fix: Instantiate an FDLE object for non-wsrep threads.

Add 'which' to REQUIRES list.
