This is the next part in the BTI index project. Overarching issue: https://github.com/scylladb/scylladb/issues/19191 Previous part: https://github.com/scylladb/scylladb/pull/25154 Next part: implementing a trie cursor (the "set to key, step forwards, step backwards" thing) on top of the `node_reader` added here. The new code added here is not used for anything yet, but it's posted as a separate PR to keep things reviewably small. This part implements the BTI trie node encoding, as described in https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/io/sstable/format/bti/BtiFormat.md#trie-nodes. It contains the logic for encoding the abstract in-memory `writer_node`s (added in the previous PR) into the on-disk format, and the logic for traversing the on-disk nodes during a read. New functionality, no backporting needed. Closes scylladb/scylladb#25317 * github.com:scylladb/scylladb: sstables/trie: add tests for BTI node serialization and traversal sstables/trie: implement BTI node traversal sstables/trie: implement BTI serialization utils/cached_file: add get_shared_page() utils/cached_file: replace a std::pair with a named struct

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
