OpenSSH No Longer Has To Depend On OpenSSL

What has been planned for a long time now, prior to the infamous heartbleed fiasco of OpenSSL (which does not affect SSH at all), is now officially a reality -- with the help of some recently adopted crypto from DJ Bernstein, OpenSSH now finally has a compile-time option to no longer depend on OpenSSL. `make OPENSSL=no` has now been introduced for a reduced configuration OpenSSH to be built without OpenSSL, which would leave you with no legacy SSH-1 baggage at all, and on the SSH-2 front with only AES-CTR and chacha20+poly1305 ciphers, ECDH/curve25519 key exchange and Ed25519 public keys.
