[compat.c compat.h sshconnect2.c sshd.c version.h] OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of connections using the curve25519-sha256@libssh.org KEX exchange method to fail when connecting with something that implements the spec properly. Disable this KEX method when speaking to one of the affected versions. reported by Aris Adamantiadis; ok markus@
