Subject:  - 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
