Felipe Moura 5e2ce6190d crypto: add CRYPTO_CHACHA20_DJB variant (64-bit counter/nonce) 
CRYPTO_CHACHA20 implements the RFC 8439/IETF parameterization (32-bit
counter + 96-bit nonce). SSH's chacha20-poly1305@openssh.com uses the
original DJB construction instead: a 64-bit block counter in state
words 12..13 and a 64-bit nonce in words 14..15 (libtomcrypt's
chacha_ivctr64). The two layouts produce different keystreams for the
same key, so an SSH server cannot interoperate with OpenSSH clients
through the IETF variant.
