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: http://tools.ietf.org/html/draft-agl-tls-chacha20poly1305-03 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. Feedback markus@, naddy@; manpage bits Loganden Velvindron @ AfriNIC ok markus@ naddy@
