Review request for hadoop-hdfs.


Summary
-------

Add listCorruptFileBlocks to DistributedFileSystem (and ClientProtocol)

As discussed in HDFS-1111, it would be beneficial for tools such as the RAID block fixer and
RAID FSCK to have access to listCorruptFileBlocks via the DistributedFileSystem (rather than
having to parse Servlet output, which could present a performance problem).

For further details, see https://issues.apache.org/jira/browse/HDFS-1482


This addresses bug HDFS-1482.
