Simplified MDL_object_lock and MDL_scoped_lock dichotomy so that they can be
stored in LF_HASH. This was done by moving out their differences to a
MDL_lock_strategy structure which is referenced from the MDL_lock object by
pointer.
Replaced m_ref_usage, m_ref_release, m_is_destroyed and m_version with single
m_state, which is updated atomically. Needed to get rid of MDL_map::m_mutex.
Adding a new virtual function MY_CHARSET_HANDLER::copy_abort().
Moving character set specific code into the correspoding implementations
(for simple, multi-byte and mbmaxlen>1 character sets).
* remove useless suppressions from the test file, when a plugin doesn't
load, the file isn't executed anyway
* add the suppression to mysql-test-run.pl instead
Take into account that PIE binaries are loaded at some offset, so
addresses cannot be directly resolved with addr2line. Find this
offset and subtract it before resolving an address.
There were two issues:
* set_var_default_role::user was overwritten with a new value,
allocated in the thd->mem_root, which is reset between executions.
That was causing the crash. Solved by introducing set_var_default_role::real_user
* when privilege tables were opened on EXECUTE, the reprepare_observer
would abort the statement (as privilege tables are opened using
the local TABLE_LIST that doesn't preserve metadata from PREPARE, so
reprepare_observer thought they're changed). This issue also applied
to SET PASSWORD. Solved by disabling reprepare_observer.
Removed 'galera-sst-mode' option from mysqldump and added logic
in wsrep_sst_mysqldump script to retrieve gtid_binlog_state from
donor node and send it to the joiner node.
Create_tmp_table was called incorrectly called in
select_materialized_with_stats::create_result_table, having keep_row_order
passed for the do_not_open parameter and keep_row_order always set to false.
file_key_management_plugin is used
Fixed error handling and added disabling InnoDB redo log encryption
if encryption key management plugin is not there.

MDEV-7399: Add support for INFORMATION_SCHEMA.INNODB_MUTEXES
MDEV-7618: Improve semaphore instrumentation
Introduced two new information schema tables to monitor mutex waits
and semaphore waits. Added a new configuration variable
innodb_intrument_semaphores to add thread_id, file name and
line of current holder of mutex/rw_lock.
Remove ONLY_IF clause in MYSQL_ADD_PLUGIN and the requirement
that every plugin's CMakeLists.txt *must* do MYSQL_ADD_PLUGIN
for PLUGIN_XXX=YES to work. This was very fragile and cannot be
relied on.
Use a different implementation of =YES check - iterate all
PLUGIN_* variables and see which one doesn't have a matching target.
Revert all ONLY_IF changes in CMakeLists.txt files.
