do_ssh1_connection: remove user input parameters.

Browse Source 
The connection protocol didn't have to do anything too complicated
with user input - just remember to check for it and turn it into
SSH1_CMSG_STDIN_DATA - so this is a much less involved change than the
previous user input conversions.
