* clarify the help text for --system-versioning-insert-history * move the vers_write=false check from Item_field::fix_fields() next to other vers field checks in find_field_in_table() * move row_start validation from handler::write_row() next to vers_update_fields() * make secure_timestamp check to happen in one place only, extract it into a function is_set_timestamp_vorbidden(). * overwriting vers fields is an error, just like setting @@timestamp * don't run vers_insert_history() for every row
