     [channels.c channels.h clientloop.c nchan.c serverloop.c]
     [session.c session.h]
     try to keep channels open until an exit-status message is sent.
     don't kill the login shells if the shells stdin/out/err is closed.
     this should now work:
     ssh -2n localhost 'exec > /dev/null 2>&1; sleep 10; exit 5'; echo ?

[channels.c channels.h serverloop.c]
     improve cleanup/exit logic in ssh2:
     stop listening to channels, detach channel users (e.g. sessions).
     wait for children (i.e. dying sessions), send exit messages,
     cleanup all channels.

[channels.c channels.h servconf.c servconf.h serverloop.c sshd.8]
     Add options ClientAliveInterval and ClientAliveCountMax to sshd.
     This gives the ability to do a "keepalive" via the encrypted channel
     which can't be spoofed (unlike TCP keepalives). Useful for when you want
     to use ssh connections to authenticate people for something, and know
     relatively quickly when they are no longer authenticated. Disabled
     by default (of course). ok markus@

[serverloop.c]
     keep the ssh session even if there is no active channel.
     this is more in line with the protocol spec and makes
        ssh -N -L 1234:server:110 host
     more useful.

Ben Lindstrom db65e8fded Please grep through the source and look for 'ISSUE' comments and verify 
that I was able to get all the portable bits in the right location.  As for
the SKEY comment there is an email out to Markus as to how it should be
resolved.  Until then I just #ifdef SKEY/#endif out the whole block.

     log() is at pri=LOG_INFO, since LOG_NOTICE goes to /dev/console on many
     systems

     1) removes fake skey from sshd, since this will be much
        harder with /usr/libexec/auth/login_XXX
     2) share/unify code used in ssh-1 and ssh-2 authentication (server side)
     3) make addition of BSD_AUTH and other challenge reponse methods
        easier.

     [auth-chall.c auth2-chall.c]
     rename *-skey.c *-chall.c since the files are not skey specific

     [readconf.c readconf.h ssh.1 sshconnect.c]
     new option: HostKeyAlias: allow the user to record the host key
     under a different name. This is useful for ssh tunneling over
     forwarded connections or if you run multiple sshd's on different
     ports on the same machine.

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.
