Previously, SSH authentication banners were displayed by calling the ordinary seat_output function, and passing it a special value in the SeatOutputType enumeration indicating an auth banner. The awkwardness of this was already showing a little in SshProxy's implementation of seat_output, where it had to check for that special value and do totally different things for SEAT_OUTPUT_AUTH_BANNER and everything else. Further work in that area is going to make it more and more awkward if I keep the two output systems unified. So let's split them up. Now, Seat has separate output() and banner() methods, which each implementation can override differently if it wants to. All the 'end user' Seat implementations use the centralised implementation function nullseat_banner_to_stderr(), which turns banner text straight back into SEAT_OUTPUT_STDERR and passes it on to seat_output. So I didn't have to tediously implement a boring version of this function in GTK, Windows GUI, consoles, file transfer etc.
