         [ssh.c ssh_config.5 sshd_config.5] Add a new protocol 2 transport
         cipher "chacha20-poly1305@openssh.com" that combines Daniel
         Bernstein's ChaCha20 stream cipher and Poly1305 MAC to build an
         authenticated encryption mode.
         Inspired by and similar to Adam Langley's proposal for TLS:
         but differs in layout used for the MAC calculation and the use of a
         second ChaCha20 instance to separately encrypt packet lengths.
         Details are in the PROTOCOL.chacha20poly1305 file.
