ssh kitten: Allow completion of ssh options between the destination and command

ssh kitten: Allow pressing Ctrl-C to abort ssh before the connection is completed
...
Fixing this involved adding a new mode to kitty where it handles
ctrl-c/z/q by sending signals to the tty foreground process group
instead of delegating to the kernel to do that. Since the pipe may be
full we have no way of knowing when the kernel will get around to
reading the signal byte. So send the signal ourselves.
