/*
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.
