This commit only replaces the bundled source and does not include any ZFS integration changes. Because the build depends on integration adjustments, it will fail until the accompanying integration commit is applied. Upstream release: https://github.com/facebook/zstd/releases/tag/v1.5.7 Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Alexander Moch <mail@alexmoch.com> Closes #18089

* Note: MEM_MODULE stops xxhash redefining BYTE, U16, etc., which are also

|
|
* Note: if you enable ZSTD_LEGACY_SUPPORT the combine.py script will need
