MDEV-20094 InnoDB blob allocation allocates extra extents
- InnoDB reserves the free extents unnecessarily during blob
page allocation even though btr_page_alloc() can handle
reserving the extent when the existing ran out of pages to be used.
MDEV-21102: Server crashes in JOIN_CACHE::write_record_data upon EXPLAIN with subqueries
JOIN_CACHE has a light-weight initialization mode that's targeted at
EXPLAINs. In that mode, JOIN_CACHE objects are not able to execute.
Light-weight mode was used whenever the statement was an EXPLAIN. However
the EXPLAIN can execute subqueries, provided they enumerate less than
@@expensive_subquery_limit rows.
Make sure we use light-weight initialization mode only when the select is
more expensive @@expensive_subquery_limit.
Also add an assert into JOIN_CACHE::put_record() which prevents its use
if it was initialized for EXPLAIN only.

MDEV-33216 stack-use-after-return in Wsrep_schema_impl::open_table()
Fix a case of stack-use-after-return reported by ASAN in
Wsrep_schema_impl::open_table(). This function has a stack allocated
TABLE_LIST object and return TABLE_LIST::table to the caller.
Changed the function to take a TABLE_LIST pointer as argument.

MDEV-33661 MENT-1591 Documenting spider_mon_table_cache and friends.
Partial documentation due to time constraints. Will improve over time.
Also removed a redundant parameter link_idx from
spider_get_sys_tables_connect_info().
And deleted some commented out code.

MDEV-26499 Fix error "mysql_shutdown failed" during MTR tests
- Fix to avoid mysqltest client getting killed abruptly during
mysql_shutdown(). When Galera replication is shutdown, wait for
THDs with `thd->stmt_da()->is_eof()` to disconnect (these are about
to disconnect anyway).
- Extract duplicate code from `wsrep_stop_replication()` and
`wsrep_shutdown_replication()` in a new function.
- No need to use a custom `shutdown_mysqld.inc` in galera
suite. Delete it, so that the one in `mysql-test/include/` is used.
