[Maria-developers] MDEV-11337 Split Item::save_in_field() into virtual methods in Type_handler

Hello Nirbhay, Can you please review a patch for 10.3: MDEV-11337 Split Item::save_in_field() into virtual methods in Type_handler It also automatically fixed two problems: MDEV-11331 Wrong result for INSERT INTO t1 (datetime_field) VALUES (hybrid_function_of_TIME_data_type) MDEV-11333 Expect "Impossible where condition" for WHERE timestamp_field>=DATE_ADD(TIMESTAMP'9999-01-01 00:00:00',INTERVAL 1000 YEAR) because the new code is now symmetric for all data types. Thanks!
