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