Fragment reordering and fragment dropping bugs have been plaguing us since forever. To fight them we added a validator to the sstable write path to prevent really messed up sstables from being written. This series adds validation to the mutation compactor. This will cover reads and compaction among others, hopefully ridding us of such bugs on the read path too. This series fixes some benign looking issues found by unit tests after the validator was added -- although how benign a producer emitting two partition-ends depends entirely on how the consumer reacts to it, so no such bug is actually benign. Fixes: https://github.com/scylladb/scylladb/issues/11174 Closes #11532 * github.com:scylladb/scylladb: mutation_compactor: add validator mutation_fragment_stream_validator: add a 'none' validation level test/boost/mutation_query_test: test_partition_limit: sort input data querier: consume_page(): use partition_start as the sentinel value treewide: use ::for_partition_end() instead of ::end_of_partition_tag_t{} treewide: use ::for_partition_start() instead of ::partition_start_tag_t{} position_in_partition: add for_partition_{start,end}()
