libprivatezstd: Restrict symbol visibility similar to upstream

We have to relax three symbols to dynamically link zstd(1), but the rest are the same.

zstd: Fix non-FreeBSD CI libzstd build

2021-01-03T15:42:00Z

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. Reported by: uqs

Unbreak ARM64 kernel build after r361426

Update to Zstandard 1.4.5

2020-05-23T21:23:46Z

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. MFC after: I won't, but feel free Relnotes: yes
