Legacy Cassandra 3.x sstables use an old bloom filter format that is incompatible with zero-copy streaming in Cassandra 5.0+. This patch automatically detects sstables with the old bloom filter format (pre-4.0) and disables zero-copy streaming for them, allowing legacy sstables to be loaded via sstableloader without requiring manual flags. The fix adds a version check in CassandraOutgoingFile.computeShouldStreamEntireSSTables() that calls descriptor.version.hasOldBfFormat() to detect legacy sstables. patch by Paulo Motta; reviewed by Stefan Miklosovic for CASSANDRA-21092
