fix parse_sshaddr error reporting
errno doesn't contain anything useful in this case
move accounting after the connection was accepted
otherwise we may end up in a weird state where we're counting connections that we don't have or have cleared a timeout without a reason.
plug memory leak in try_to_connect
it should call conn_free to cleanup the connection struct now.
bind_socket early
so that if it fails the user is promptly notified. This requires us to make sure that fds 0-2 are opened, so steal the same trick slowcgi have.
