"While aa8c2cbc16 'Merge "Migrate sstables
to flat_mutation_reader" from Piotr' has converted the low-level sstable
reader to the new flat_mutation_reader interface there were still
multiple readers related to sstables that required converting,
including:
- restricted reader
- filtering reader
- single partition sstable reader
This series completes their conversion to the flat stream interface."
