Zstandard compression tools
Zstd, short for Zstandard, is a lossless compression algorithm,
targeting real-time compression scenarios at zlib-level compression ratio.
Zstd can also offer stronger compression ratios at the cost of
compression speed. Speed vs. compression trade-off is configurable by
small increments. Decompression speed is preserved and remains
roughly the same at all settings, a property shared by most LZ
compression algorithms, such as zlib or lzma.

(revision 23)
- Revert the addition of build specific cmake files: breaks
gdal, apache-arrow and possibly others -- boo#1211566
* note that shipping cmake files is not intentional or supported
upstream at the moment: gh#facebook/zstd#3642
- Add cmake files manually because we do not want to add
cmake to the bootstrap ring0
- update to 1.5.5:
* fix: fix rare corruption bug affecting the high compression
mode, reported by @danlark1
* perf: improve mid-level compression speed
* lib: deprecated bufferless block-level API (#3534) by
@terrelln
* cli: mmap large dictionaries to save memory, by
@daniellerozenblit
* cli: improve speed of --patch-from mode (~+50%) (#3545) by
@daniellerozenblit
* cli: improve i/o speed (~+10%) when processing lots of small
files (#3479) by @felixhandte
* cli: zstd no longer crashes when requested to write into
write-protected directory (#3541) by @felixhandte
* cli: fix decompression into block device using -o, reported
by @georgmu
* misc: improve seekable format ingestion speed (~+100%) for
very small chunk sizes (#3544) by @Cyan4973
* misc: tests/fullbench can benchmark multiple files (#3516) by
@dloidolt
- Build AVX2 enabled hwcaps library for x86_64-v3
