zstandard is the successor to lz4, there are attempts to integrate zstandard in
ZFS, Allan Jude is working on that, I am working on integrating in libstand to
allow to boot a kernel compressed with zstandard or a mfsroot with zstandard,
which would benefit lots of pxe users.

I have also added it to newsyslog(8) so users can benefit zstandard compression
for the log files, which will consume less CPUs for greater compression that
bzip2. On low ended boxes with low storage this is actually very useful as well.

I haven't checked yet the performances on my armv6 boxes, but on the low ended
recent atom laptops I can tell this is already very useful.
