ssh_socket_connect always non-blocking

[Nick Burrett <nick@xxxxxxxxxx>]

Maybe I'm missing something, but, ssh_socket_connect() only ever connects
in non-blocking mode.  There is a defined ssh_connect_host() for blocking
connections but it is never referenced.  Looks like the logic to check for
a connected callback is missing and choose the correct connection function
is missing.
