 * ChaCha20_ctr32 encrypts |len| bytes from |inp| with the given key and
 * nonce and writes the result to |out|, which may be equal to |inp|.
 * The |key| is not 32 bytes of verbatim key material though, but the
 * said material collected into 8 32-bit elements array in host byte
 * order. Same approach applies to nonce: the |counter| argument is
 * pointer to concatenated nonce and counter values collected into 4
 * 32-bit elements. This, passing crypto material collected into 32-bit
 * elements as opposite to passing verbatim byte vectors, is chosen for
 * efficiency in multi-call scenarios.
