Add support for repacking condensed sparse files
This commit broadly does the following things: - Rename and move the sparse mapping structure to libutil - Add a function to the data writer for writing condensed versions of sparse files, given the mapping. - This shares code with the already existing function for regular files. The shared code is moved to a common helper function. - Add support to tar2sqfs for repacking sparse files. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
