fix regression I introduced in 4.2: X11 forwardings initiated after
a session has exited (e.g. "(sleep 5; xterm) &") would not start.

Fix a number of X11 forwarding channel leaks:
1. Refuse multiple X11 forwarding requests on the same session
2. Clean up all listeners after a single_connection X11 forward, not just
the one that made the single connection
3. Destroy X11 listeners when the session owning them goes away

race when efd gets closed while there is still buffered data:
change CHANNEL_EFD_OUTPUT_ACTIVE()
1) c->efd must always be valid AND
2a) no EOF has been seen OR
2b) there is buffered data

bz#413: allow optional specification of bind address for port forwardings.
Patch originally by Dan Astorian, but worked on by several people
Adds GatewayPorts=clientspecified option on server to allow remote
forwards to bind to client-specified ports.

fix some window size change bugs for multiplexed connections: windows sizes
were not being updated if they had changed after ~^Z suspends and SIGWINCH

setup x11 listen socket for just one connect if the client requests so.

sshd X11 fake server will now listen on localhost by default:
$ echo $DISPLAY
localhost:12.0
$ netstat -an|grep 6012
tcp 0 0 127.0.0.1.6012 *.* LISTEN
tcp6 0 0 ::1.6012 *.* LISTEN
sshd_config gatewayports=yes can be used to revert back to the old
behavior. will control this with another option later. ok markus@

[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@
