[clientloop.c kex.c kex.h serverloop.c sshconnect2.c sshd.c]
     enable server side rekeying + some rekey related clientup.
     todo: we should not send any non-KEX messages after we send KEXINIT

[kex.c kex.h kexdh.c kexgex.c packet.c sshconnect2.c sshd.c]
     don't sent multiple kexinit-requests.
     send newkeys, block while waiting for newkeys.
     fix comments.

[kex.c kex.h packet.c sshconnect2.c sshd.c]
     undo parts of recent my changes: main part of keyexchange does not
     need dispatch-callbacks, since application data is delayed until
     the keyexchange completes (if i understand the drafts correctly).
     add some infrastructure for re-keying.

[dh.c dh.h kex.c kex.h sshconnect2.c sshd.c]
     move kex to kex*.c, used dispatch_set() callbacks for kex. should
     make rekeying easier.

[kex.c kex.h sshconnect2.c sshd.c]
     generate a 2*need size (~300 instead of 1024/2048) random private
     exponent during the DH key agreement. according to Niels (the great
     german advisor) this is safe since /etc/primes contains strong
     primes only.

Ben Lindstrom 46c162204b One way to massive patch. <sigh> It compiles and works under Linux..
And I think I have all the bits right from the OpenBSD tree.

     add support for RSA to SSH2.  please test.
     there are now 3 types of keys: RSA1 is used by ssh-1 only,
     RSA and DSA are used by SSH2.
     you can use 'ssh-keygen -t rsa -f ssh2_rsa_file' to generate RSA
     keys for SSH2 and use the RSA keys for hostkeys or for user keys.
     SSH2 RSA or DSA keys are added to .ssh/authorised_keys2 as before.
 - (djm) Fix up Makefile and Redhat init script to create RSA host keys

     First rough implementation of the diffie-hellman group exchange.  The
     client can ask the server for bigger groups to perform the diffie-hellman
     in, thus increasing the attack complexity when using ciphers with longer
