MDEV-29878 Galera test failure on MDEV-26575
Test MDEV-26575 fails when it runs after MDEV-25389. This is because
the latter simulates a failure while an applier thread is
created in `start_wsrep_THD()`. The failure was not handled correctly
and would not cleanup the created THD from the global
`server_threads`. A subsequent shutdown would hang and eventually fail
trying to close this THD.
MDEV-29512 deadlock between commit monitor and THD::LOCK_thd_data mutex
This commit contains only a mtr test for reproducing the issue in MDEV-29512
The actual fix will be pushed in wsrep-lib repository
The hanging in MDEV-29512 happens when binlog purging is attempted, and there is
one local BF aborted transaction waiting for commit monitor.
The test will launch two node cluster and enable binlogging with expire log days,
to force binlog purging to happen.
A local transaction is executed so that will become BF abort victim, and has advanced
to replication stage waiting for commit monitor for final cleanup (to mark position in innodb)
after that, applier is released to complete the BF abort and due to binlog configuration,
starting the binlog purging. This is where the hanging would occur, if code is buggy

MDEV-29880 Galera test failure on GCF-336
Fix `wsrep_table_accessible_when_detached()` so that commands that
access no tables are rejected while a node is disconnected from a
cluster.
MDEV-24412 InnoDB: Upgrade after a crash is not supported
recv_log_recover_10_4(): Widen the operand of bitwise and to 64 bits,
so that the upgrade check will work when the redo log record is located
more than 4 gigabytes from the start of the first file.
MDEV-30106 InnoDB fails to validate the change buffer on startup
ibuf_init_at_db_start(): Validate the change buffer root page.
A later version may stop creating a change buffer, and this
validation check will prevent a downgrade from such later versions.
ibuf_max_size_update(): If the change buffer was not loaded, do nothing.
dict_boot(): Merge the local variable "error" to "err". Ignore
failures of ibuf_init_at_db_start() if innodb_force_recovery>=4.
MDEV-30089 Metrics not incremented for 1st iteration in buf_LRU_free_from_common_LRU_list()
In commit a03dd94be804a4b8b1406696920834bb2c0bedbd as well as
mysql/mysql-server@6ef8c343445a26aaf9ebd76d72cf57db44b481f5
the iterations were changed so that the variable "scanned"
would remain 0 when the first list item qualifies for eviction.
buf_LRU_free_from_unzip_LRU_list(), buf_LRU_free_from_common_LRU_list():
Increment "scanned" when a block can be freed.
buf_LRU_free_from_common_LRU_list(): Remove a redundant condition.
Whenever this function is invoked, buf_pool.LRU should be nonempty,
hence something should always be scanned.
MDEV-25417: Remove innodb buffer pool load throttling
The very lightest of load would decimate any buffer pool loading
to ~1 page per second. As seen in MDEV-29343 this resulting in
a load taking over an hour on a high end system.
Since MDEV-26547 the fetching is asynchronous, however the loading
has equal access to the IO as the SQL queries.
