flat_mutation_reader_v2 was introduced in a pair of commits in 2021:e3309322c3"Clone flat_mutation_reader related classes into v2 variants"08b5773c12"Adapt flat_mutation_reader_v2 to the new version of the API" as a replacement for flat_mutation_reader, using range_tombstone_change instead of range_tombstone to represent represent range tombstones. See those commits for more information. The transition was incremental; the last use of the original flat_mutation_reader was removed in 2022 in commit026f8cc1e7"db: Use mutation_partition_v2 in mvcc" In turn, flat_mutation_reader was introduced in 2017 in commit748205ca75"Introduce flat_mutation_reader" To transition from a mutation_reader that nested rows within a partition in a separate stream, to a flat reader that streamed partitions and rows in the same stream. Here, we reclaim the original name and rename the awkward flat_mutation_reader_v2 to mutation_reader. Note that mutation_fragment_v2 remains since we still use the original for compatibilty, sometimes. Some notes about the transition: - files were also renamed. In one case (flat_mutation_reader_test.cc), the rename target already existed, so we rename to mutation_reader_another_test.cc. - a namespace 'mutation_reader' with two definitions existed (in mutation_reader_fwd.hh). Its contents was folded into the mutation_reader class. As a result, a few #includes had to be adjusted. Closes scylladb/scylladb#19356
