xxHash v0.8.0 - Stable XXH3

Stable XXH3

After more than a year in the making, XXH3 has finally reached stable status, \ 
for both its 64-bit and 128-bit variants.
While the code itself was in good enough shape for production use, the generated \ 
values could still change between versions. This limited XXH3 to local sessions \ 
only.
From now on, output values produced by XXH3 for a given input and parameter set \ 
will remain identical across systems and across future versions. It makes it \ 
possible to store these values for later comparison, or to exchange them across \ 
network connections.

BSD-style checksums

Official stabilization being the main goal of this release, there are only \ 
minimal additional changes.
A notable one though is the ability for xxhsum CLI to produce and check \ 
BSD-style checksum lines, using command --tag.
One advantage of --tag format is that it explicitly specifies the algorithm and \ 
format used to represent the checksum. For example, it explicitly mentions if a \ 
checksum value follows the canonical format (XXH32) or the alternative \ 
little-endian format (XXH32_LE).
Generating BSD-style checksum lines was actually already possible, but as the \ 
CLI was unable to --check them, it remained a hidden option.
This situation changes with v0.8.0, thanks to a patch by @WayneD which makes it \ 
possible to --check BSD-style checksum lines.

xxhash: updated to 0.7.4

xxHash v0.7.4 - Finalizing XXH3 and XXH128

xxHash v0.7.4 is the last evolution of xxh3 and xxh128, primarily designed to \ 
finalize the algorithm.
It is considered release candidate for v0.8.0, which means that if all goes \ 
right, this version will rebranded v0.8.0, almost "as is", within the \ 
next few weeks, after receiving sufficient feedback.
v0.8.0 is the official version after which XXH3 and XXH128 are considered \ 
"stabilized", meaning that return values will never change given the \ 
same input and seed, making the hash suitable for long-term storage and \ 
transmission.

Beyond these "final touches", the new version also brings a few \ 
notable improvements.

Log message:
xxhash: Update to 0.7.3. Fix installation of libs.

v0.7.3
- perf: improved speed for large inputs (~+20%)
- perf: improved latency for small inputs (~10%)
- perf: s390x Vectorial code, by @easyaspi314
- cli: improved support for Unicode filenames on Windows, thanks to @easyaspi314 \ 
and @t-mat
- api: `xxhash.h` can now be included in any order, with and without \ 
`XXH_STATIC_LINKING_ONLY` and `XXH_INLINE_ALL`
- build: xxHash's implementation transferred into `xxhash.h`. No more need to \ 
have `xxhash.c` in the `/include` directory for `XXH_INLINE_ALL` to work
- install: created pkg-config file, by @bket
- install: VCpkg installation instructions, by @LilyWangL
- doc: Highly improved code documentation, by @easyaspi314
- misc: New test tool in `/tests/collisions`: brute force collision tester for \ 
64-bit hashes

v0.7.2
- Fixed collision ratio of `XXH128` for some specific input lengths, reported by \ 
@svpv
- Improved `VSX` and `NEON` variants, by @easyaspi314
- Improved performance of scalar code path (`XXH_VECTOR=0`), by @easyaspi314
- `xxhsum`: can generate 128-bit hashes with the `-H2` option (note: for \ 
experimental purposes only! `XXH128` is not yet frozen)
- `xxhsum`: option `-q` removes status notifications

v0.7.1
- Secret first: the algorithm computation can be altered by providing a \ 
"secret", which is any blob of bytes, of size >= \ 
`XXH3_SECRET_SIZE_MIN`.
- `seed` is still available, and acts as a secret generator
- updated `ARM NEON` variant by @easyaspi314
- Streaming implementation is available
- Improve compatibility and performance with Visual Studio, with help from @aras-p
- Better integration when using `XXH_INLINE_ALL`: do not pollute host namespace, \ 
use its own macros, such as `XXH_ASSERT()`, `XXH_ALIGN`, etc.
- 128-bit variant provides helper functions for comparison of hashes.
- Better `clang` generation of `rotl` instruction, thanks to @easyaspi314
- `XXH_REROLL` build macro to reduce binary size, by @easyaspi314
- Improved `cmake` script, by @Mezozoysky
- Full benchmark program provided in `/tests/bench`

Log message:
devel/xxhash: Import xxhash 0.6.5.

xxHash is an Extremely fast Hash algorithm, running at RAM speed
limits. It successfully completes the SMHasher test suite which
evaluates collision, dispersion and randomness qualities of hash
functions.
