on top of implementations, which were already scoped out.

  * 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
