* If you want to include _and expose_ xxHash functions from within your own
* library, but also want to avoid symbol collisions with other libraries which
* may also include xxHash, you can use @ref XXH_NAMESPACE to automatically prefix
* any public symbol from xxhash library with the value of @ref XXH_NAMESPACE
* (therefore, avoid empty or numeric values).
*
* Note that no change is required within the calling program as long as it
* includes `xxhash.h`: Regular symbol names will be automatically translated
* by this header.
