This patch fixes not only the assertion failure in the function
Field_iterator_table_ref::set_field_iterator() but also:
- fixes the problem of forced materialization of derived tables used
in subqueries contained in WHERE clauses of single-table and multi-table
UPDATE and DELETE statements
- fixes the problem of MDEV-17954 that prevented execution of multi-table
DELETE statements if they use in their WHERE clauses references to
the tables that are updated.
The patch must be considered a complement to the patch for MDEV-28883.

The fix for "MDEV-17698 MEMORY engine performance regression"
previously fixed this problem.
- Adding the test for MDEV-17724
- Re-recording wrong results for tests:
* engines/iuds/r/insert_number
* engines/iuds/r/update_delete_number
which started to fail since MDEV-17698
- as of 5.5.27, YEAR(2) is deprecated, hence the new warning;
- MDEV-553 - different error code/message on out-of-range autoincrement;
- INSERT IGNORE now produces a warning if a duplicate was encountered (change pushed along with MDEV-553)
Following reasons caused mismatches:
- different handling of invalid values;
- different CAST results with fractional seconds;
- microseconds support in MariaDB;
- different algorithm of comparing temporal values;
- differences in error and warning texts and codes;
- different approach to truncating datetime values to time;
- additional collations;
- different record order for queries without ORDER BY;
- MySQL bug#66034.
