Remodel file extraction tools to use libfstream
This commit rewrites the libtar write paths to use libfstream insead of a FILE pointer. Also, the libcommon file extraction function is remodeled to use libfstream. In accordance, rdsquashfs, sqfs2tar and sqfsdiff have some minor adjustments made to work with the ported libtar and libcommon. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
