[kex.c kex.h kexdh.c kexdhc.c kexdhs.c kexgex.c kexgexc.c kexgexs.c]
     remove hardcoded hash lengths in key exchange code, allowing
     implementation of KEX methods with different hashes (e.g. SHA-256);

[kex.c kex.h myproposal.h packet.c packet.h servconf.c session.c]
     [sshconnect2.c sshd.c sshd_config sshd_config.5]
     add a new compression method that delays compression until the user
     has been authenticated successfully and set compression to 'delayed'
     for sshd.
     this breaks older openssh clients (< 3.5) if they insist on
     compression, so you have to re-enable compression in sshd_config.
