CVE fixes, security hardening and new options for Mksquashfs/Unsquashfs.

Please see the INSTALL file for instructions on installing the tools,
and the USAGE file for documentation on how to use the tools.

Summary of changes

1. Mksquashfs now generates reproducible images by default.  Mkfs time and
   file timestamps can also be specified.

2. Support for the Zstandard (ZSTD) compression algorithm has been added.

3. Pseudo files now support symbolic links.

4. CVE-2015-4645 and CVE-2015-4646 have been fixed.

Squashfs is a highly compressed read-only filesystem for Linux. It
uses either gzip/xz/lzo/lz4/zstd compression to compress both files,
inodes and directories. Inodes in the system are very small and all
blocks are packed to minimise data overhead. Block sizes greater than
4K are supported up to a maximum of 1Mbytes (default block size 128K).
Squashfs is intended for general read-only filesystem use, for archival
use (i.e. in cases where a .tar.gz file may be used), and in constrained
block device/memory systems (e.g. embedded systems) where low overhead is
needed.
This package contains tools to manipulate squashfs archive files.
