Fix non-FreeBSD CI build after v1.4.8. This definition was only used in
zstd(1), which isn't part of non-FreeBSD CI (I guess). The ifdef was
added in v1.4.5 import.
Upstream does not currently support shared-linked zstd(1), but I have
proposed https://github.com/facebook/zstd/pull/2450 . If that is
adopted, we can add -DZSTD_PROGRAMS_LINK_SHARED to our libzstd build and
drop some diffs.

As usual, the full release notes are found on Github:
https://github.com/facebook/zstd/releases/tag/v1.4.5
Notable changes include:
* Improved decompress performance on amd64 and arm (5-10%
and 15-50%, respectively).
* '--patch-from' zstd(1) CLI option, which provides something like a very fast
version of bspatch(1) with slightly worse compression. See release notes.
In this update, I dropped the 3-year old -O0 workaround for an LLVM ARM bug;
the bug was fixed in LLVM SVN in 2017, but we didn't remove this workaround
from our tree until now.

Notable changes in this release include improved decompression speed (about
10%). See the Github release notes for more details.

Our in-tree gcc doesn't have a no-tree-vectorize optimization knob, so we get a
warning that it's unused. This causes the build to fail on all our gcc platforms.
Add a quick version check as a stop-gap measure to get CI building again.
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

Plenty of allocation sites pass M_ZERO and sizes which are small and known
at compilation time. Handling them internally in malloc loses this information
and results in avoidable calls to memset.
Instead, let the compiler take the advantage of it whenever possible.

Includes our local patch to conditionalize use of __builtin_clz(ll) on
Clang's __has_builtin() (which is just defined to false when building with
GCC).
The issue is tracked upstream at https://github.com/facebook/zstd/pull/884 .
Otherwise, these are vanilla Zstandard 1.3.4 files.

Link __bswap[ds]i2() intrinsics in to libzstd for riscv, where the C runtime
apparently lacks such intrinsics.

Silence a Coverity warning about 'windowSize' being uninitialized.
(Yes, nothing that calls this routine actually uses the windowSize
value. Still, appeasing Coverity is pretty harmless in this case.)

The definitions otherwise leak into anything that includes zstd.h,
which is not desirable for native FreeBSD code.

This is in contrib code but since we only have mallocarray(9) in current
we will not upstream this.
This effectively brings back r327934, which was reverted to correct the
log message.
Add an implementation of the intrinsics invoked by __builtin_ctz{,ll} and
__builtin_clz{,ll}, and include this compilation unit on platforms that lack
assembly intrinsics for those builtins (MIPS and RISC-V).
Future cleanup work might involve bringing these into a mini libcompiler-rt
for the standalone kernel environment. Or cleaning up the approach upstream
takes for builtins in standalone environments (or just FreeBSD). For now,
at least this builds, and doesn't require modifying the vendor code.

This change was made to allow zstd(1) to be a dropin replacement for gzip(1) and
friends, allowing easy integration, in particular with newsyslog(8). At the
price of having a zstd(1) command which by default behaves differently than what
upstream default, confusing users.
newsyslog(8) has been adapted to now be more flexible in what it accepts as
compression program, so we can switch back zstd(1) to its default behaviour
