            I have no further objections against pushing bb-10.10-MDEV-25704 as of 7f422495 into 10.10 main and releasing it with 10.10.1.

            fixed most. Debug builds only of query_cache test failing because args[0]->can_eval_in_optimize() changes from false to true between Item_func_random_bytes::fix_length_and_dec and Item_func_random_bytes::val_str. This is due to args[0]->table->const_table becoming true.

            As suggested, I implemented this at the end of bb-10.10-MDEV-25704 and tested for mysql 8,0 compatibility. select random_bytes(0) is our extension. Note the fixme on TIME conversion in the test. Suggestions on implementing this much appreciated.
