Now that the client can listen on sockets (#2406), we can enhance the packet handlers to make this feature more useful:
Done:
Examples with a server (any), and a client started using:
xpra attach --bind-tcp=0.0.0.0:10001
xpra info tcp://127.0.0.1:10001 | grep backing.type
xpra control tcp://127.0.0.1:10001 debug enable x11
xpra control tcp://127.0.0.1:10001 show_session_info
xpra control tcp://127.0.0.1:10001 show_bug_report
etc..
