Generation stamp value should be validated when creating a Block
----------------------------------------------------------------

                 Key: HADOOP-5413
                 URL: https://issues.apache.org/jira/browse/HADOOP-5413
             Project: Hadoop Core
          Issue Type: Improvement
          Components: dfs
            Reporter: Tsz Wo (Nicholas), SZE


In hdfs, generation stamps < GenerationStamp.FIRST_VALID_STAMP are reserved values but not valid generation stamps.  Incorrect uses of the reserved values may cause unexpected behavior.  We should  validate generation stamp when creating a Block.
