Add support for application-specific typecodes to typed bytes
-------------------------------------------------------------

                 Key: HADOOP-5450
                 URL: https://issues.apache.org/jira/browse/HADOOP-5450
             Project: Hadoop Core
          Issue Type: Improvement
          Components: contrib/streaming
            Reporter: Klaas Bosteels
            Assignee: Klaas Bosteels


For serializing objects of types that are not supported by typed bytes serialization, applications
might want to use a custom serialization format. Right now, typecode 0 has to be used for
the bytes resulting from this custom serialization, which could lead to problems when deserializing
the objects because the application cannot know if a byte sequence following typecode 0 is
a customly serialized object or just a raw sequence of bytes. Therefore, a range of typecodes
that are treated as aliases for 0 should be added, such that different typecodes can be used
for application-specific purposes.
