+  Convenience function for writing meta data to a SquashFS image
+
+  This function internally creates a meta data writer and writes the given
+  'data' blob with 'table_size' bytes to disk, neatly partitioned into meta
+  data blocks. For each meta data block, it remembers the 64 bit start address,
+  writes out all addresses to an uncompressed list and returns the location
+  where the address list starts in 'start'.
+
+  Returns 0 on success. Internally prints error messages to stderr.
