    [SPARK-16862] Configurable buffer size in `UnsafeSorterSpillReader`

    ## What changes were proposed in this pull request?
    
    Jira: https://issues.apache.org/jira/browse/SPARK-16862
    
    `BufferedInputStream` used in `UnsafeSorterSpillReader` uses the default 8k buffer to
read data off disk. This PR makes it configurable to improve on disk reads. I have kept the
default value to be same as it was before (8k) so there would not be any change in current
behavior.
    
    ## How was this patch tested?
    
    I am relying on the existing unit tests.
