This merge brings in a couple new files, which needed to be attached to the
build; a new dependency on <limits.h>, which must be stubbed; and a name
change in the Context parameter constants, from ZSTD_p_foo to ZSTD_c_foo.
Significantly, it fixes a kernel build error with GCC where floating-point
functions were included in the kernel build, by hiding them under the same
compile-time #ifdef that already covered their invocation. That issue was
introduced to FreeBSD in the 1.3.7 update and tracked upstream here:
https://github.com/facebook/zstd/issues/1386
The full 1.3.8 release notes can be found on Github:

Relnotes: yes
Import the wrapper script from zstdgrep (written by wiz@netbsd.org)
Modify it to support more than just zstd (adding support for gzip,
lzma, xz and bzip2)
Write a simple manpage dedicated for it.
Only use that new wrapper both for gnu grep and bsd grep
Next step will be removing code related to compression format from bsdgrep

Among new things it is now threaded by default, use zstd -T# to chose the
number of threads not that -T0 will automatically determine the number of
threads based on the number of CPU online.
