[~jesse_yates] Whatever is easiest for you.  I wouldn't mind rolling it into trunk because

> To avoid copying data during restore snapshot we need to introduce an HFile Link  that
allows to reference a file that can be in the original path (/hbase/table/region/cf/hfile)
or, if the file is archived, in the archive directory (/hbase/.archive/table/region/cf/hfile).
