[chacha.h cipher-chachapoly.h digest.h hmac.h kex.h kexc25519.c] [misc.h poly1305.h ssh-pkcs11.c defines.h] revert __bounded change; it causes way more problems for portable than it solves; pointed out by dtucker@

[chacha.h cipher-chachapoly.h digest.h hmac.h kex.h kexc25519.c [misc.h poly1305.h ssh-pkcs11.c] use __bounded(...) attribute recently added to sys/cdefs.h instead of longform __attribute__(__bounded(...)); for brevity and a warning free compilation with llvm/clang

[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. Feedback markus@, naddy@; manpage bits Loganden Velvindron @ AfriNIC ok markus@ naddy@
