- Big OpenBSD CVS update (mainly beginnings of SSH2 infrastructure)

   - [auth.c session.c sshd.c auth.h]
     split sshd.c -> auth.c session.c sshd.c plus cleanup and goto-removal
   - [bufaux.c bufaux.h]
     support ssh2 bignums
   - [channels.c channels.h clientloop.c sshd.c nchan.c nchan.h packet.c]
     [readconf.c ssh.c ssh.h serverloop.c]
     replace big switch() with function tables (prepare for ssh2)
   - [ssh2.h]
     ssh2 message type codes
   - [sshd.8]
     reorder Xr to avoid cutting
   - [serverloop.c]
     close(fdin) if fdin != fdout, shutdown otherwise, ok theo@
   - [channels.c]
     missing close
     allow bigger packets
   - [cipher.c cipher.h]
     support ssh2 ciphers
   - [compress.c]
     cleanup, less code
   - [dispatch.c dispatch.h]
     function tables for different message types
   - [log-server.c]
     do not log() if debuggin to stderr
     rename a cpp symbol, to avoid param.h collision
   - [mpaux.c]
     KNF
   - [nchan.c]
     sync w/ channels.c
