Log message:
Change the counter argument for CRYPTO_chacha_20 to be 64-bits on all platforms.
The recently-added EVP_aead_chacha20_poly1305_ietf() function, which implements
informational RFC 7539, "ChaCha20 and Poly1305 for IETF Protocols", needs a
64-bit counter to avoid truncation on 32-bit platforms.
The existing TLS ChaCha20-Poly1305 ciphersuite is not impacted by this, but
making this change requires an ABI bump.
