  High level helper function to serialize an entire file system tree to
  a squashfs inode table and directory table. The super block is update

  The function internally creates two meta data writers and uses
  meta_writer_write_inode to serialize the inode table of the fstree.

  Returns 0 on success. Prints error messages to stderr on failure.
  The filename is used to prefix error messages.
