    ORC-248. PhysicalFsWriter sometimes passes negative padding down to shims

    The PhysicalFsWriter sometimes pass down negative sizes for padding, which leads to exceptions.
    My fix:
    * Add a new option to enable writing variable length HDFS blocks "orc.write.shortened.blocks",
which is off by default.
    * Modified the shim to shortenBlock so that the PhysicalFsWriter can track the offsets.
    * shortenBlock isn't gated by the padding tolerance, although it is called when the new
stripe would cross a block boundary.
