/* Note : This is a slightly modified version of xxHash
* for zstd internal usage.
* Modifications are :
* - Removal of XXH3 / XXH128 algorithms, unused within zstd
* - prefix names of all symbols, to reduce risks of collisions
* - Replace malloc / free / memcpy by Zstandard's variants
* This could be achieved at build stage, with CPPFLAGS typically,
* but doing it directly within source file
* make it possible for 3rd party to simply grab the directory
* and compile it locally, with whichever build system they wish,
* without a need for them to configure some build flag.
