[PATCH 2/2] lib/zstd: mark some internal functions as static with ZSTD_STATIC

["Adeodato Simó" <dato@net.com.org.es>]

Use ZSTD_STATIC instead of vanilla static because the functions are
actually unused, and the macro adds the unused attribute.

This silences -Wmissing-prototypes when defining.

I separated these two functions into a separate patch because they
are actually unused.

If you'd rather have them removed, we may do that as well.

Note that the ZSTD_STATIC macro adds the unused attribute in addition
to static, but it adds __inline as well.
