Avro IDL supports includes:
http://avro.apache.org/docs/current/idl.html#imports. It does not support
extensions, to the best of my knowledge. Perhaps you could file a feature
request at https://issues.apache.org/jira/browse/AVRO?

You could make a union of all of the primitive types? I'm not sure exactly
what you're trying to accomplish with this question though.
