[cipher-chachapoly.c]
     Call chacha_ivsetup() immediately before chacha_encrypt_bytes() - this
     makes it easier to verify that chacha_encrypt_bytes() is only called once
     per chacha_ivsetup() call.

     New key API: refactor key-related functions to be more library-like,
     existing API is offered as a set of wrappers.

     Thanks also to Ben Hawkes, David Tomaschik, Ivan Fratric, Matthew
     Dempsky and Ron Bowes for a detailed review a few months ago.

     NB. This commit also removes portable OpenSSH support for OpenSSL
     <0.9.8e.

[Makefile.in PROTOCOL PROTOCOL.chacha20poly1305 authfile.c chacha.c]
     [chacha.h cipher-chachapoly.c cipher-chachapoly.h cipher.c cipher.h]
     [dh.c myproposal.h packet.c poly1305.c poly1305.h servconf.c ssh.1]
     [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:
     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.
