New backend flag indicating support for CONF_ssh_nc_host.

Browse Source 
This flag is set in backends which can be used programmatically to
proxy a network connection in place of running a shell session. That
is true of both SSH proper, and the psusan ssh-connection protocol.

Nothing yet uses this flag, but something is about to.
