Added code to support that force index can be used to force an index scan
instead of a full table scan. Currently this code is disable but I added
a test to verify that things works if the code is ever enabled.
Other things:
- FORCE INDEX will now work with "Range checked for each record" and
join cache (see main/type_time_6065)
- Removed code ifdef with BAD_OPTIMIZATION (New cost calculations should
fix this).
- Removed TABLE_LIST->force_index and comment that it should be removed
- Added TABLE->force_index_join and use in the corresponding places.
This means that FORCE INDEX FOR ORDER BY will not affect keys used
in joins anymore.
Remove TODO that the above should be added.
I still kept TABLE->force_index as it's used in
test_if_cheaper_ordering() and opt_range.cc
- Removed setting table->force_index when calling test_quick_select() as
it's not needed (force_index is an argument to test_quick_select())
Use SELECT_LEX to save lists for ORDER BY and GROUP BY before parsing
WINDOW clauses / specifications. This is needed for proper parsing
of a nested WINDOW clause when a WINDOW clause is used in a subquery
contained in another WINDOW clause.
Fix assignment of empty SQL_I_List to another one (in case of empty list
next shoud point on first).
Consistent with MDEV-4206 and empty log_slow_filter still means
no explict filtering. Since 21518ab2e453 however the
log_queries_not_using_indexes became stored in the same variable.
As we need to test for the absense of log_queries_not_using_indexes
the SERVER_QUERY_NO_INDEX USED part of log_slow_statement, the empty
criteria resulted in an always true to log queries not using indexes if
log_slow_filter was set to empty.
Adjusted the log_slow.test for MDEV-4206 as slow_log_query has been
global and session for a while and it was relying on the MDEV-21187
buggy behavior to detect a slow query.

Fix `wsrep_table_accessible_when_detached()` so that commands that
access no tables are rejected while a node is disconnected from a
cluster.

=========== Problem =============
- `show columns` is not working for temporary tables, even though there
is enough privilege `create temporary tables`.
=========== Solution =============
- Append `TMP_TABLE_ACLS` privilege when running `show columns` for temp
tables.
- Additionally `check_access()` for database only once, not for each
field
=========== Additionally =============
- Update comments for function `check_table_access` arguments
