Add support for Unix domain socket forwarding. A remote TCP port
may be forwarded to a local Unix domain socket and vice versa or
both ends may be a Unix domain socket. This is a reimplementation
of the streamlocal patches by William Ahern from:

unbreak remote portforwarding with dynamic allocated listen ports:
1) send the actual listen port in the open message (instead of 0).
this allows multiple forwardings with a dynamic listen port
2) update the matching permit-open entry, so we can identify where
to connect to

[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.

[mux.c]
"atomically" create the listening mux socket by binding it on a temorary
name and then linking it into position after listen() has succeeded.
this allows the mux clients to determine that the server socket is
either ready or stale without races. stale server sockets are now
automatically removed

[channels.c channels.h mux.c ssh.c]
Pause the mux channel while waiting for reply from aynch callbacks.
Prevents misordering of replies if new requests arrive while waiting.
Extend channel open confirm callback to allow signalling failure
conditions as well as success. Use this to 1) fix a memory leak, 2)
start using the above pause mechanism and 3) delay sending a success/
failure message on mux slave session open until we receive a reply from
the server.

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.

[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).
