329301d2e6 MDEV-23562 Assertion `time_type == MYSQL_TIMESTAMP_DATETIME' failed upon SELECT from versioned table 
The code in vers_select_conds_t::init_from_sysvar() assumed that
the value of the system_versioning_asof is DATETIME.
But it also could be DATE after a query like this:
  SET system_versioning_asof = DATE(NOW());

Fixing Sys_var_vers_asof::update() to convert the value
of the assignment source to DATETIME if it returned DATE.

Now vers_select_conds_t::init_from_sysvar() always gets a DATETIME value.

1b5cf2f7e7 Safe session_track_system_variables snapshot 
When enabling system variables tracker, make a copy of
global_system_variables.session_track_system_variables
under LOCK_global_system_variables. This protects from concurrent variable
updates and potential freed memory access, as well as from variable
reconstruction (which was previously protected by LOCK_plugin).

We can also use this copy as a session variable pointer, so that we don't
have to allocate memory and reconstruct it every time it is referenced.

For this very reason we don't need buffer_length stuff anymore.

As well as don't we need to take LOCK_plugin early in ::enable().
Unified ::parse_var_list() to acquire LOCK_plugin unconditionally.
For no apparent reason it wasn't previously acquired for global
variable update.

554ac6f393 Allocate Session_sysvars_tracker statically 
One less new/delete per connection.

Removed m_mem_flag since most allocs are thread specific. The only
exception are allocs performed during initialization.

Removed State_tracker and Session_tracker constructors as they don't make
sense anymore.

No reason to access session_sysvars_tracker via get_tracker(), so access
it directly instead.

Timestamp-based versioning for InnoDB [closes #209] 
* Removed integer_fields check
* Reworked Vers_parse_info::check_sys_fields()
* Misc renames
* versioned as vers_sys_type_t

* Removed versioned_by_sql(), versioned_by_engine()

versioned() works as before;
versioned(VERS_TIMESTAMP) is versioned_by_sql();
versioned(VERS_TRX_ID) is versioned_by_engine().

* create_tmp_table() fix
* Foreign constraints for timestamp-based
* Range auto-specifier fix
* SQL: 1-row partition rotation fix [fixes #260]
* Fix 'drop system versioning, algorithm=inplace'
