jni data content stream offset>0 fix
Many updates in support of 'getParent' changes (see AUT-725).
Update FsContent.getFileSystem() to do a DB query rather than crawl the
hierarchy to the FileSystem.  Also added clause for throwing
TskCoreException.
Updated AbstractContent.getParent to not throw an exception when getting
the parent of an Image; returns null instead.
