           Force a clean shutdown of ControlMaster client sessions when the ~. escape
           sequence is used.  This means that ~. should now work in mux clients even
           if the server is no longer responding.  Found by tedu, ok djm.

           [PROTOCOL.mux clientloop.c clientloop.h mux.c]
           improve our behaviour when TTY allocation fails: if we are in
           RequestTTY=auto mode (the default), then do not treat at TTY
           allocation error as fatal but rather just restore the local TTY
           to cooked mode and continue. This is more graceful on devices that
           never allocate TTYs.
      
           If RequestTTY is set to "yes" or "force", then failure to allocate
           a TTY is fatal.

           [channels.c channels.h clientloop.c clientloop.h mux.c nchan.c ssh.c]
           rewrite ssh(1) multiplexing code to a more sensible protocol.
      
           The new multiplexing code uses channels for the listener and
           accepted control sockets to make the mux master non-blocking, so
           no stalls when processing messages from a slave.
      
           avoid use of fatal() in mux master protocol parsing so an errant slave
           process cannot take down a running master.
      
           implement requesting of port-forwards over multiplexed sessions. Any
           port forwards requested by the slave are added to those the master has
           established.
      
           add support for stdio forwarding ("ssh -W host:port ...") in mux slaves.
      
           document master/slave mux protocol so that other tools can use it to
           control a running ssh(1). Note: there are no guarantees that this
           protocol won't be incompatibly changed (though it is versioned).

           Enable ~ escapes for multiplex slave sessions; give each channel
           its own escape state and hook the escape filters up to muxed
           channels. bz #1331
           Mux slaves do not currently support the ~^Z and ~& escapes.
           NB. this change cranks the mux protocol version, so a new ssh
           mux client will not be able to connect to a running old ssh
           mux master.

           Use new channel status confirmation callback system to properly deal
           with "important" channel requests that fail, in particular command exec,
           shell and subsystem requests. Previously we would optimistically assume
           that the requests would always succeed, which could cause hangs if they
           did not (e.g. when the server runs out of fds) or were unimplemented by
           the server (bz #1384)
           Also, properly report failing multiplex channel requests via the mux
           client stderr (subject to LogLevel in the mux master) - better than
           silently failing.
