[mux.c] set "detach_close" flag when registering channel cleanup callbacks. This causes the channel to close normally when its fds close and hangs when terminating a mux slave using ~. bz#1758; ok markus@

[mux.c] kill correct channel (was killing already-dead mux channel, not its session channel)

[mux.c] fix bug introduced in mux rewrite: In a mux master, when a socket to a mux slave closes before its server session (as may occur when the slave has been signalled), gracefully close the server session rather than deleting its channel immediately. A server may have more messages on that channel to send (e.g. an exit message) that will fatal() the client if they are sent to a channel that has been prematurely deleted. spotted by imorgan AT nas.nasa.gov

[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). feedback Salvador Fandino, dtucker@ channel changes ok markus@

[mux.c sshpty.h clientloop.c sshtty.c] quell tc[gs]etattr warnings when forcing a tty (ssh -tt), since we usually don't actually have a tty to read/set; bz#1686 ok dtucker@

[mux.c] fall back to creating a new TCP connection on most multiplexing errors (socket connect fail, invalid version, refused permittion, corrupted messages, etc.); bz #1329 ok dtucker@

[clientloop.h channels.h clientloop.c channels.c mux.c] The multiplexing escape char handler commit last night introduced a small memory leak per session; plug it.

[clientloop.h mux.c channels.c clientloop.c channels.h] 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. ok dtucker@

[clientloop.c clientloop.h ssh.c mux.c] tidy up session multiplexing code, moving it into its own file and making the function names more consistent - making ssh.c and clientloop.c a fair bit more readable. ok markus@
