Everyone is welcome.

This is intentional. Since this is generated code, the Real source is
interface/cassandra.genavro.
In a perfect world we'd do the same for Thrift, but since that would
make the Thrift compiler a build dependency (requiring everyone who
builds from source to build the Thrift compiler from source), we commit
the generated source to SVN and ship it in the source artifacts.

They're used to implement the Avro-based RPC interface. "Clients" are
implemented in Avro which can be downloaded from that project's site
(http://avro.apache.org). FWIW, this is the same for Thrift.
