    Uppity: allow running multiple independent servers.
    
    I've moved all the results of the command-line config options into a
    small struct instead of having them be local variables of main(). We
    maintain an array of those structs; most command-line options modify
    the last element in the array; and we respond to the new special
    option '--and' by appending a fresh struct to the end of the array and
    initialising it to default values.
    
    So now, if I want two or three SSH servers running on different ports
    with separately configured host keys, banners, etc, I can do that with
    a single command line along the lines of:
    
      ./uppity --listen 2222 --hostkey this.ppk --bannertext "this" \
         --and --listen 2223 --hostkey that.ppk --bannertext "that"
    
    There's a single number space of connections used in log messages, and
    each new connection reports which of the servers it connects to.
    
    This is only a marginally useful feature: there's not much it does
    that couldn't have been done just as well by running multiple Uppitys
    each in their own process. But when I do want several servers at once
    (which I've been using recently to test the jump-host system), it's
    quite nice to have them all producing a single combined stream of log
    data and all conveniently killable with a single ^C.
